PRESSBOARD FOR VELVET, ETC

Filed Feb. 8, 1958 INVENTOR zz/LWM PatentedFeJ. 13, 94 v UNITED stares y PRESSBARD FOR'VELYT; tra

Y My invention relates to improvements in what are commonly called pressboards used for pressing velvet, velours and other nap or pile fabrics such as set forth inmy former Patents Nos. Re. 16,194 and 1,485,825. l i

These devices comprise multiply `woventextile -fabric foundations having wire pins vsecured therein. These wires are usually ofwsteel and frequently rust out under the alternate steaming and drying to which they are subjectedin use.

The pins are frequently displaced when` pressure is applied unlessa suitable support Vis, provided Vsuch as a wire meshwork stitched to the cloth foundation. This is satisfactory for many cases but the stitching is expensive if done properly. If not done properly, the stitching displaces `the pins so as to leave a pattern of the displaced pins on the fabric which is pressed on `the board.

lThis stitching also sometimes rotsor rust's out or is otherwise destroyed.

I- also sometimes employ tubular members to permit the passage of steam through the foundaf-v tion and it is diicult to hold them inl-place.

After many years of experimentation and study Ihave discovered that these dicultieslmaybe solved by securing the wire loops of adjacent pms y together at the yback of the cloth foundation by soldering,` brazing or welding. m p 1 Figure 1 is an enlarged fragmentary section of a pressboard embodying one iforml'ofI my invention.` l M l Figurel 2 is a view of the baclrfof` the same device, parts `being broken away. p

Figure 3 is aviewv of the back of a modified form of my invention. f

Figure4 is a sectional View showing the connecting metal being sprayed on. m l

The foundation 'l is usually formed of a number of layers of fwoven cotton duck stitched or cemented together. `The points of the pins 8 are inserted through thefoundation leavingthe loop portionsv 9 at the back and resting against They are usually arrangedmalong inclined lines as shown in Fig. 2; The eyelets or tubular `members lll are the' surface `of the vrearmost-` layer.

inserted from the' back betweenrows4 of pins leaving their flanges at the back. A fine mesh wire ll may be applied to the vback to hold the pins and tubes in place. l

The anchorage of the pins may be effected in several ways. Forinstance byl applying solder l2'along thelines of the pinloops connecting said loops. "I'his not onlyreinforces the pins a and holds them in place but coats them so that suitably impregnated with the protective compins to each other and to the wire meshwork.

` posed on the opposite face thereof, a layer of wire'mesh covering said loop portions and oppo- `site faceof the foundation and a coating of solder 'over said wire mesh whereby said wire mesh and l vthere is no dangerof theirrusting where the y solder'is applied. I l v rIhe wire mesh maybe soldered, brazec'l` or weldedto the backs of the pins so as to hold them securely in place. `5

A suitable paint or coating compoundl3 may f be applied to the foundation between the rows thepins so as to assist in preventing corrosion` or rusting of kthe wires. The y. fabric` may be pound before or afterthe pins are inserted. l

In place` of the strips'of solder l2, I; may apply a layer I4 of solder as indicated in Fig. 3.

. A metallic film or layer maybe applied to the backs of the pins by means of Va hot spray l5 so as to permanently; connect the Wires. In all f to it in `which case part of thexspray will pass through the meshwork and unite the, pins and 25 the meshwork. l

A suitable so-called liquid solder or cold'solder or metallic paint or cementmay be applied ,to

the *back of the board either directly to the cloth meshwork (if used) in which latter case the liquid will `penetrate the meshwork and bind the l I claimz` l l l y l. A pressing device comprising acloth founvdation having U-shaped needles,` the points of saidy `needles projecting" from one face of' said foundation and the loop portions resting exloopportionsi are connected to prevent displacementr of the needles, y l x i 4` l '2.' A pressing devicecomprising a cloth founvdation having tubularuidflow members passp the entire area of the device, and .a connection,`

of soldei` between the `loop portions of theneedles andthe `tubular membersjto prevent'the 55` needles and tubular members from Working loose. 3. A flexible pressing device comprising a cloth foundation having U-shaped needles, the points .of said needles projecting from one face of said solder penetrating the-,wire mesh and connectn ingvsaid wire mesh directly lto the loop portions to prevent displacement of the needles. 4. A pressing device comprising a cloth foun- ,dation having U-shaped needles arranged in ,'rows, the pointsfof said needles projecting from one face of said foundation and the loop portions resting against the opposite face thereof, a layer `of wire mesh coveringv said loop portions and said opposite face of the foundation and thin strips of solder following the rows of the needles overvlying and penetrating the wire mesh atintervals and connecting said loop portions to the wire mesh to prevent displacement of the needles,

Aadjacent strips being spacedfrom each other.

5. A pressing device comprising a cloth foundation having U-shaped needles arranged in spaced parallel rows, the points oi said needles projecting from one face of said foundation and the loop portions resting against the opposite face thereof, a layer of wire mesh covering said loop portions and said opposite face of the foundation, thin strips of solder following the rows of needles in their parallel and spaced relationship connecting said wire mesh loop portions to prevent displacement' of the needles and spacedtuloular fluid -flow members in spaces between the parallel strips and extending through the foundation. l
