Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for sewing cloth tape onto the surface of a base fabric of a summer comforter, blanket, sheet, etc., and an apparatus used in this method.

Cloth tape is sometimes sewn onto the surface of the base fabric of summer comforters, blankets, etc. for decoration or marking purposes. The work efficiency is low because it is done manually using
In addition, the sewing line tends to bend easily, resulting in a poor appearance, and it is cumbersome to mark a line on the base fabric to indicate the sewing position before starting work.

This departure! The above-mentioned tape sewing work can be carried out efficiently by using an existing quilting machine.

As shown in FIG. 1, the method of this invention utilizes a quilting machine 1 that continuously quilts a base fabric such as a blanket. A tape supply means 3 is provided, the tape T is supplied from the supply means 3 onto the surface of the base fabric B, and the tape T is sewn onto the surface of the base fabric B with quilting stitches by the operation of the sewing needle portion 2. It is characterized by

Further, the details of the device used in the method of this invention will be explained based on an embodiment shown in FIGS. 2 and 3. In the head of the quilting machine 10, there are a number of sewing needles 2 having the same structure along the width direction. They are arranged in a row, and the receiving portions 2a are provided opposite to each other on the lower side thereof.

A pair of thread guide bars 4 are provided above the sewing needle portion 2.
, 4' are horizontally suspended parallel to each other.

□A support member consisting of an arm 5, a ball 6, etc. is attached to the bars 4, 4', and a tape spool 7 is rotatably supported around the horizontal axis via this support member. As shown in FIG. 2, the arm 5 constituting the support member has two bars 4, 4' between its base and the presser piece 8.
The ball 6 is inserted and erected into the insertion portion 9 at the tip of the arm 5. A support shaft 11 is attached to the ball 6 via a bracket 10, and the spool 7 is supported on this support shaft 11.

12 is a stopper fitted to the spindle 11; 13 is a presser spring interposed between the stopper 12 and the spool 7;
4 is a tapered collar.

On the other hand, a tape guide 16 is provided from the lower side of the tape spool 7 to the presser foot 15 to guide the tape while bending both edges thereof.

This tape guide 16 is supported by a fixture 17 attached to one bar 4Kffi. In FIG. 2, 18 is a roll of base fabric, and 19 is a guide plate.

The apparatus of the present invention has the above-mentioned configuration, and when sewing tape, the sewing needle part 2 is set at a desired position in the width direction of the original fabric, and the tape spool 7 and tape guide 16 are arranged above and in front of the sewing needle part 2. The tape T that has been fixed and pulled out from the spool 7 is passed through the tape guide 16 and pressed against the presser foot 1.
Lead below 5. After that, when the quilting machine is operated, the base fabric B and the tape T are attached to the lower side of the specified sewing needle part 2.
are taken in in a superimposed state, and by the action of the sewing needle part 2, both are successively sewn with quilting stitches and sent out.

According to the method of the present invention, it is possible to automatically sew the tape onto the surface of the base fabric in its length direction, and the sewing speed is extremely fast compared to the conventional manual method, thereby reducing inefficiency. It's expensive, and you can use your existing quilting machine as is.
It can be implemented inexpensively.

Further, in the apparatus of the present invention, since the tape supply and sewing are performed at a constant position in the width direction of the base fabric, the seams are straight and the sewing has a beautiful appearance.

In particular, the device of this invention utilizes a thread guide bar and has a spool and tape guide thereon, so by moving the spool and tape guide on the bar, the positions can be set freely. Accurate positioning is possible. Furthermore, the spool and tape guide can move left and right together with the thread guide bar and sewing needle, so even when sewing a zigzag on a quilting machine, the presence of the spool and tape guide does not get in the way, making it easy to attach these parts. It can also be used as a conventional quilting machine without any problems.

It should be noted that, in contrast to the embodiments of FIGS. 2 and 3, the supply means consisting of a spool or tape guide can also be attached to the fixed frame of the quilting machine.
