A method is mentioned.

<Embodiment 1>
When the knitting of the sofa cover is started from the back surface of the “convex” -shaped sofa cover, the respective parts of the sofa cover 100 are knitted in accordance with the knitting procedure shown in FIGS. The “convex” -shaped back surface 1 shown in FIG. 2 (E) has a rectangular base knitted fabric portion 10 and a rectangular protruding knitted fabric that protrudes from one side (the upper side of the sofa cover) of the base knitted fabric portion 10. Part 11. At this time, of the sides provided on the “convex” -shaped back surface 1, all the sides except the sides on the lower side of the sofa cover (sides ab in the figure) are locked to the needle bed. The knitting process of knitting the “convex” back surface 1 will be described with reference to FIGS.

  3 and 4, “alphabet + number” is the number of the knitting process, A to Z, A ′ to E ′ are the positions of the knitting needles of the front needle bed (FB) and the rear needle bed (BB), a to h. Indicates a position on the needle bed corresponding to each vertex of the “convex” -shaped back surface 1 shown in FIG. In the knitting steps of FIGS. 3 and 4, ◯ is a stitch, V is a hook, and the portion where the knitting operation is actually performed in each knitting step is indicated by a bold line. Moreover, the schematic diagram of the latching state of the back surface 1 in the key of the knitting process of these FIG.3, 4 is shown in FIG. For convenience of explanation, the number of knitting needles shown in FIGS. 3 and 4 is smaller than the actual knitting, the number of hooks and stitches in FIGS. 3 and 4 and the hooks and stitches in FIG. It does not match the number of latches.

  In knitting the “convex” back surface 1, the knitting needles G, I, K, M, O, Q of the FB and the knitting needles H, J, L, N, P, R of the BB are alternately knitted (S1). ). Next, after knitting the stitches on the knitting needles S of the FB, a new stitch row following the set-up stitch row composed of the stitches of the BB is knitted (S2). The hook knitted in S2 is located substantially opposite to the stitch at the end in the moving direction of the stitch row that is knitted in S2 and moved in the next S3, and the side db (right side) shown in FIG. Part of

  Next, the stitches locked to the BB are moved to the right by 2 stitches by two stitches (S3). After that, the stitches are knitted on the knitting needles H of the BB that have become empty needles by the movement of S3, and then in S3. A new stitch row following the wale direction of the moved stitch row is knitted (S4). Here, the stitch knitted in S4 is a part of the side c-a (left side) shown in FIG.

  Further, after forming a stitch on the knitting needle U of the FB, a new stitch row is knitted following the stitch row knitted in S2 and moved in S3 (S5), and the stitch row knitted in S5 is 2 in the right direction on the paper surface. The needle is moved one by one (S6). Then, after forming stitches on the knitting needles J of the BB that became empty needles at the transfer of S6, a new stitch row following the stitch row transferred at S6 is knitted (S7).

  Thereafter, the same knitting as S5 to S7 is repeated to complete the rectangular base knitted fabric portion 10 (cdba) shown in FIG. The locked state of each side of the base knitted fabric portion 10 is shown in S8 of FIG. 4 and FIG. 5 (A). Sides c-a (left side) and a-b (lower side) in the base knitted fabric portion 10 are locked to BB, and sides b-d (right side) and dc (upper side) are locked to FB.

  Next, the protruding knitted fabric portion 11 protruding from the side cd which is one side of the base knitted fabric portion 10 is knitted. In the knitting of the protruding knitted fabric portion 11, the side ab is subjected to a bind-off process in this embodiment. This bind-off process is a process for forming the lower opening of the sofa cover 100, and a known method can be used. The locked state of the base knitted fabric portion 10 subjected to the bind off process is shown in S9 of FIG. 4 and FIG. 5 (B).

  From the state of S9, the protruding knitted fabric portion 11 protruding from the middle portion of the side cd of the base knitted fabric portion 10 is knitted. Among the hooks forming the sides cd and sides db of the base knitted fabric portion 10 locked to the FB during the knitting, the middle of the side cd consisting of the hooks locked to the knitting needles K and M The stitch row is left as it is, and the remaining stitches are transferred in a direction away from the stitches locked by the knitting needles K and M (S10, FIG. 5C). In S10, the hook forming the side c-a locked to the BB is also moved by two stitches toward the outside in the knitting width direction. The movement of the hook latched by BB is performed so that the transition yarn between FB and BB in the vicinity of the vertex c does not extend. With this transfer of S10, as shown in FIG. 5C, empty needles (knitting needles I and O of the FB) are formed within the knitting width of the side cd of the base knitted fabric portion 10.

  Next, while moving the yarn feeder in one direction, the stitches are knitted on the knitting needles I, O of the FB that have become empty needles by the transfer of S10, and the stitch row is locked to the knitting needles K, M of the FB. Subsequently, a new stitch row is formed (S11, FIG. 5D). The hook of the knitting needle I of the FB knitted in S11 is a part of the side e-g, and the hook of the knitting needle O is a part of the side f-h.

  Next, the stitch row locked to the knitting needles K and M of the FB is set as an intermediate stitch row, and the stitches locked to the FB and BB are separated from the stitch row while leaving only the intermediate stitch row as it is in S10. The direction is transferred by two stitches in the direction (S12). Then, similarly to S11, the stitches are formed on the knitting needles I and O of the FB that have become empty needles by the transfer of S12, and a new stitch row following the stitch row that is locked to the knitting needles K and M of the FB is formed. Knit (S13). Thereafter, by repeating the same knitting as in S12 and S13, as shown in S14, the back surface 1 in which all sides except the sides ab are locked to the FB or BB is knitted.

When the knitting of the back surface 1 described above is completed, the sofa cover 100 shown in FIGS. 2A to 2D is knitted using the back surface 1 as a set-up surface. Specifically, a C-shaped turn back knitting is performed on the hooks and stitches locked to the FB and BB shown in S14, and as shown in FIGS. 2 (B) and 2 (D), the top surface of the headrest of the sofa and organizing side, and portions corresponding to the side surface of the backrest (consolidated surface). Thereafter, the front of the headrest (FIG. 2 (A)) → the backrest (FIG. 2 (A)) → the seat and the armrest are included in the order of the numbers shown in the arrows shown in FIGS. 2 (A) to 2 (D). The body corresponding to the main body (FIG. 2 (B), (D)) → front end surface (FIG. 2 (A)) is knitted, and finally the lower end portion of the front end surface is subjected to a bind-off process so that the sofa cover 100 is removed. Finalize. In addition, the knitting order on the left and right of the front end face can be changed.

When the front end surface of the “concave” sofa cover is knitted and the sofa cover is knitted continuously without sewing on the front end surface, the front end is opposite to the procedure with reference to FIGS. Surface 2 (see FIG. 2 (F)) → main body including seat and armrest → backrest → front surface of headrest → part corresponding to rear surface of main body is knitted to complete sofa cover 100. Hereinafter, with reference to FIGS. 6 and 7 which are knitting process diagrams of the “concave” -shaped front end face 2 and FIG. 8 which is a schematic diagram showing a locking state of the front end face 2 at the main points of the knitting process, The knitting procedure of the front end face 2 in the shape of "" will be described. 6 and 7 are the same as FIGS. 3 and 4, and FIG. 8 is the same as FIG.

  In knitting the “concave” -shaped front end surface 2, the stitches are knitted on the knitting needles B, D, F, H, J, L, and N of the BB (T1). Next, after knitting stitches on the knitting needles O of the FB, a new stitch row following the stitches of the BB is knitted (T2). The hook knitted at T2 is at a position almost opposite to the stitch at the end in the moving direction of the stitch row to be moved at the next T3, and becomes a part of the side io shown in FIG.

  Next, the stitches locked to the BB are moved to the right in the drawing by two stitches (T3), and then the stitches are knitted on the knitting needles B of the BB that have become empty needles by the transfer of T3, and at T3 A new stitch row following the transferred stitch row is knitted (T4). The hook knitted at T4 is a part of the side j-1 shown in FIG.

  Thereafter, by repeating the same knitting as in T2 to T4, the rectangular base knitted fabric portion 20 (FIG. 2 (F)) is knitted as shown in T5 and FIG. 8 (A). Sides j-l and l-o in the base knitted fabric portion 20 are locked to the BB, and the side i-o is locked to the FB.

  When the base knitted fabric portion 20 is completed, the hooks on the side j-1 of the base knitted fabric portion 20 knitted on the knitting needles B, D, and F of the BB are transferred to the knitting needles K, I, and G of the FB (T6, FIG. 8 (B)). As will be described later, this transfer is to leave the BB knitting needles so that the stitch row of the protruding knitted fabric portion 21 can be knitted when the protruding knitted fabric portion 21 is knitted.

  Next, as shown at T7 in FIG. 7, among the stitches constituting the side l-o of the base knitted fabric portion 20, the end stitch row on the left side of the paper surface that is locked by the knitting needles H and J of the BB is the left side of the paper surface. And the end stitch row on the right side of the paper, which is locked by the knitting needles T and R of the BB, is transferred to the right side of the paper by two stitches (FIG. 8C). Then, the knitting needles J, H, F and the knitting needle E of the FB are fed to knitting a stitch row which becomes a part of the protruding knitted fabric portion 21, and the knitting needles R, T, V of the BB and the knitting needle U of the FB are knitted. And knitting a stitch row that becomes a part of the protruding knitted fabric portion 22 (T8, FIG. 8D). The stitches knitted on the knitting needle E of the FB, the knitting needle J of the BB, the knitting needle R of the BB, and the knitting needle U of the FB at T8 are the sides ln, km, pr, and o in FIG. -Part of q.

  Thereafter, the transfer shown in T9 and the knitting of the stitch row shown in T10 are repeated to complete the front end face 2 shown in FIG. The locked state in the needle bed of the completed front end face 2 is shown in T11.

  As shown in T11, the sides j-1, ln, io, oq of the front end face 2 are FB, the sides nm, mk, kp, pr, rq. Is locked to BB and is in a state where the stitch rows following these sides can be knitted. Therefore, the sofa cover 100 is completed by knitting in the knitting order opposite to the knitting order indicated by the white arrows and numbers in FIGS. 2A to 2D with the front end face 2 as a set-up surface. Can be made. However, for the back surface shown in FIG. 2C, knitting is performed from the upper end to the lower end, and the bind off process is performed at the lower end position.

  Here, in the knitting process using FIGS. 6 and 7, two yarn feeders are used for knitting the protruding knitted fabric portions 21 and 22, but both protruding knitted fabric portions 21 and 22 are knitted with one yarn feeder. You can also. In this case, after the protruding knitted fabric portion 21 is knitted to the upper end, knitting is performed in the order of n → m → k → p in FIG.

<Modified Embodiment>
In addition, this invention is not necessarily limited to embodiment mentioned above, In the range which does not deviate from the summary of this invention, it can change and implement embodiment mentioned above suitably. For example, the above-described base knitted fabric portion 10 (20) in FIGS. 2E and 2F is rectangular, but the turn knitting is performed to gradually reduce the knitting width of the side cd (l-o). Thus, the base knitted fabric portion 10 (20) other than the rectangle can be knitted. For example, as shown in FIG. 9 (A), in the process of knitting the base knitted fabric portion, turn-back knitting is performed by sequentially reducing the knitting width from both ends in the knitting width direction toward the center of the knitting width direction of the base knitted fabric portion. The dome-shaped base knitted fabric portion 30 can be knitted. In addition, as shown in FIG. 9 (B), by performing turn-back knitting in which the knitting width is sequentially reduced starting from one end side in the knitting width direction of the base knitted fabric portion in the process of knitting the base knitted fabric portion, a trapezoidal shape is obtained. The base knitted fabric portion 40 can be knitted.

  In addition, in the base knitted fabric portion 10 shown in FIG. 2 (E), the protruding knitting is also performed on the side ab facing the side cd knitting the protruding knitted fabric portion 11, the side ac, and the side bd. The ground portion 11 may be formed. For example, when the protruding knitted fabric portion 11 is formed on the side cd, the protruding knitted fabric portion protruding from the base knitted fabric portion 10 is also knitted on the side ab without performing the bind off process in S10 of FIG. Then, the cross-shaped set-up surface shown in FIG. 9C can be knitted.
