Description

[Detailed explanation of the idea] The present invention relates to a free width tape sewing foot.

In conventional tape sewing presses, the bias tape folding width is constant, and the trumpet-shaped guides that determine the folding width are fixed to each width.

Therefore, it is necessary to prepare tape sewing presses of various widths, which is very uneconomical, so you end up preparing only the standard one, and the others are very difficult to sew bias tape. It was a state.

This invention was devised to solve the problems of conventional products, and is a general-purpose product that allows the bias tape width to be freely selected and allows various tape widths to be set with a single tape sewing foot. The purpose of the present invention is to provide a highly durable tape sewing foot.

Hereinafter, the present invention will be explained according to an illustrative embodiment.

A is a free-width tape sewing foot, in which the base end 201 of the arm 200 of the tape holder 2 is fixed to the side of the presser main body 1, the holder main body 203 faces the front of the presser main body 1, and the The holder main body 203 is provided with a tape sewing width adjusting device 3.

There are two projecting pieces 10 on the sides of the left ear piece 101 of the presser main body 1.
2, 102 is raised up, and the protruding pieces 102, 102 fit into the through holes 202, 202 drilled in the base end 201 of the arm 200 of the tape holder 2 and are tightened, thereby fixing the holder 2. It looks like this.

4 is a needle hole.

The tape holder 2 has a forked shape with a tip 202 of an arm 200 extending upward.

The forked right piece 204 has a holder main body 2.
03 is provided integrally and rises at a continuous slope.

On the other hand, the forked left piece 205 also curves upward at a continuous slope.

These left piece 205 and right piece 204 have screw holes 206,
206 is engraved and open, and an adjustment screw 6 pivotally supported by an adjustment nut 5 of an adjustment device 3, which will be described later, is screwed through the adjustment screw 206.

Friction serrations 501 are carved on the outer periphery of the adjustment nut 5.

The holder main body 203 consists of upper and lower pieces 203a and 203b that are open to the right and in the front-rear direction.The horizontal length of these pieces is about 15 cm, and the upper piece 203a has a scale 7 extending from the right to the left. These upper and lower pieces 203a are displayed.
, 203b, a tape guide 8 constituting the adjustment device 3 is interposed so as to be slidable left and right so as not to cause play.

The tape guide 8 has a sliding piece 800 having a tape guide groove 801 on the right side, and a guide piece 802 extending leftward is integrally provided at the front end of the slide piece 800, and is fixed to the right end of the adjustment screw 6 described above.

The guide piece 802 has a reference line 9 aligned with the scale 7.
is displayed vertically, and the guide piece 802 is connected to the upper and lower pieces 203a formed on the front end surface of the right piece 204.
, 203b.

In the adjustment device 3, the above-mentioned adjustment nut 5 is located in a bifurcated groove 208 and is threadably supported by an adjustment screw 6 passing through a screw hole 206. It is fitted and fixed into the hole 803 that is provided.

Next, the free width tape sewing foot A configured as described above is
Explain the main effects of

First, the position of the tape guide 8 is adjusted in accordance with the width of the tape to be sewn (not shown).

For the adjustment, a finger is brought into contact with the peripheral surface serrations 501 of the adjustment nut 5 and rotated.

At this time, the tape guide 8 has upper and lower pieces 203a, 20
3 Slide inside b to the left or right.

When the reference line 9 matches the predetermined scale 7, the rotation of the nut 50 is stopped and the guide is stopped.

Next, with the tape wrapped around the fabric edge, the tape is inserted so that the edge of the tape contacts the deep part of the groove 801, and is sent below the presser main body 1 to drive a sewing machine (not shown). As mentioned above, in the present invention, the proximal end of the tape holder is fixed to the side of the presser main body, and the holder main body is moved to the front of the presser main body. The main body of the holder has a movable tape guide for adjusting the tape sewing width and a free width tape sewing foot, so one tape sewing foot can be used to sew multiple tapes of different widths. It has the advantages of being freely adjustable, increasing its operating rate, and being extremely economical for the user.
