Description

[Detailed explanation of the invention] The core of the label (collar) of jackets such as suits and formal wear is usually made of interlining 11 and the bottom, as shown in Figure 2, in order to give the label a rounded appearance and create a decorative effect. It is manufactured by sewing the cloth 12 in a curved position with the interlining 11 side protruding while being overlapped with each other.

Conventionally, as a machine for sewing the interlining 11 and the lower cloth 12 for the label core, as shown in FIG. 3, the interlining 11 and the lower cloth 12 are overlapped, and While the interlining 11 is slack with respect to the lower fabric 12, while being transferred along the curved path A, sewing is carried out using the sewing needle 6 provided near the top a on the lower side in the direction of transport than the curved top a of the path A. A label interlining sewing machine, which is designed to be used as a base material, is used.

Specifically, the arcuate top surfaces 1a of the pair of opposing plates 1, 1
. The friction body 3 is fixed, and a feed roller 4 is mounted on a shaft so as to be freely driven and rotatable, while at least one of the opposing pulling rollers 5, 5 is mounted on a shaft on the outside of the other plate 1 so that at least one of them can be driven and rotated. In addition, a presser plate 7 is disposed in front of the sewing needle 6 on the lower side of the fabric bender 2, that is, the curved apex a, and the upper interlining 11 and the lower lower fabric in a superposed state are separated by the feed roller 4. 12 and the interlining 11 by exerting a frictional action on the lower cloth 12 of the friction body 3.
The feed speed for the label core is set higher than that for the lower cloth 12, the interlining 11 is transported while being slackened with respect to the lower cloth 12, and the label core is sewn with a sewing needle 6, thereby giving the label core a rounded appearance.

However, in this case, the slack portion 13 of the interlining due to the feed speed difference tends to be closer to the upper side than the bender 2 due to the pressure of the sewing needle 6 and presser plate 7, and even if the feed speed for the interlining 11 is increased. However, it was difficult to give the label core the desired large and smooth roundness.

In view of these circumstances, the present invention aims to provide a label core sewing machine that can give the label core the desired large and smooth roundness and sew the interlining and bottom fabric with only extremely simple structural improvements. It is something to do.

The label interlining sewing machine according to the present invention is characterized in that a presser for pressing the interlining toward the lower fabric is provided at a midway portion of the curved path on the upper side in the transport direction than the curved top.

That is, by the pressing action of the presser against the interlining, the slack portion of the interlining can be moved to a state where it wraps around to the lower side than the top of the path curve, and the sewing needle can enter into this transitional slack portion. Compared to conventional products, the interlining and base material can be sewn with a larger and smoother roundness, and therefore labels made using the label interlining made in this way can be This allows for a good decorative effect.

Further, the structure for this purpose requires only an extremely simple modification of providing a presser, and has the advantage that it can be implemented economically even on existing machines.

In addition, if the above-mentioned presser is configured so that the amount of pressure applied to the interlining can be changed and adjusted, it will be possible to change the design of the jacket.
It has the advantage of being able to freely select the roundness and curvature of the label core, and also being able to cope well with changes in the type of fabric.

Also, if the contact surface of the presser foot with the interlining is made smooth,
This has the advantage that the sagging portion can wrap around the top of the curve even better, and the interlining will not be damaged.

Hereinafter, embodiments of the present invention will be described based on FIG. 1.

That is, in the label core sewing machine configured in the same manner as shown in FIG. A presser 8 is provided to press the interlining 11 toward the lower fabric 12, that is, downward.

This presser 8 is configured to be vertically slidably fitted into the fixing part 9 and fixed in position with a bolt 10, and at least on its lower surface, that is, on the interlining 11.
The contact surface 8a is smoothly constructed.

By this presser 8, the slack part of the interlining is divided into a lower part 13A and an upper part 13B in the transfer direction, and the lower slack part 13A goes around the bender 2 to the lower part.

This wrapping state occurs when the interlining 11 is sewn by the pulling rollers 5, 5. This is maintained by the simultaneous pulling action of the lower cloth 12 at the same speed.

The rotation speed of the feed roller 4 is the pull roller 5,
It is set slightly larger than that of 5.

The distance between the contact surface 8a of the presser 8 and the top surface 1a of the plate 1 is normally about 3 mm.

Further, as a feeding device with a speed difference, any combination of the friction body 3 and the feed roller 4 may be used, and as a pulling device, an opposed pulling roller 5,
Anything other than 5 is fine.
