Description

Field of application of the invention

The application relates to a device for holding down suture legs of tubular curved workpieces, in particular for ironing machines of the textile industry.

Characteristic of the known state of the art

According to DD-PS 117090 (D06F71 / 18) is called a device for ironing preparation of seams, which is particularly intended for use on a combination of sewing and ironing machine and has two rails for guiding the seam and a means for transferring the seam legs , The disadvantage of this device is that the solution is technically complex and for the opening of the suture limb only an air flow is used, which can not prevent tipping over the same on one side at not completely zontrischer leadership of the suture limbs, the same is this device for tubular curved workpieces not suitable. According to DE-AS 2528348 (D06F71 / 30) is also a device for ironing preparation of seams for Durchlaufbügelmaschinun known in which a wedge-shaped suture leg opener for automatically opening and spreading the suture leg is used. In DD-PSK 227469 (D06F71 / 18) a device for ironing tubular fabric is called, where by means of pivoting seam spreader the seam is spread, while at the curvature of a special seam spreader, with which the seam must be spread by hand, is installed.

A disadvantage of the facilities is that a guarantee of the suture spread when entering the ironing machine is not given, especially in tubular curved workpieces such as sleeves.

Object of the invention

The aim of the invention is to provide a device which ensures the holding down of suture legs, especially in the case of curved seams.

Explanation of the essence of the invention

The invention has for its object to develop a device for holding down suture limbs, especially in curved seams, with which the tipping over of the suture leg when entering the ironing machine is avoided. According to the invention, this is essentially achieved by holding the seam, which is pre-spread by means of a seam spreader, when it is retracted into an ironing device by means of a seam leg retainer until it has been ironed out in the spread state. The starting position returns to the starting days after completing the ironing process.

embodiment

The invention will be explained below using an exemplary embodiment.

According to the accompanying drawing, the seam ironing station 4 is directly preceded by a lower shoe operating station.

The shuttle 5 moves with the ironing material located on the bracket 3 in the seam ironing station 4 a. The seam to be ironed is spread when retracted by means of the seam spreader 6 and held in place by the seam leg retainer 2 in the spread state. When retracting the shuttle 5 in the Nahtbügelpreßstation 4 of the seam leg restraints 2 comes form match between the ironing, which lies on the bracket spar 3, and the seam strap element 1 and thus holds the suture leg to the ironing process. After completion of the ironing process, the shuttle 5 moves out of the seam ironing station 4. The ironed piece can be removed. The suture limb 2 returns to the starting days.

Claims (2)

1. A device for holding down the suture of tubular curved curved workpieces textile fabrics, characterized in that during retraction of the shuttle (5) in the Nahtbügelpreßstation (4) on the bracket spar (3) resting suture legs pre-spread through the suture spreader (6) and through the Nahtschenkelniederhalter (2) are held until the pressing in the spread state and go back to the initial position after the pressing process. 2. Apparatus according to claim 1, characterized in that the suture leg lower holder (2) preferably consists of spring steel. For this 1 page drawing Λ \ Field of application of the invention The application relates to a device for holding down suture legs of tubular curved workpieces, in particular for ironing machines of the textile industry. Characteristic of the known state of the art According to DD-PS117090 (D06F71 / 18) there is mentioned a device for ironing preparation of seams, which is particularly intended for use on a combination of sewing machine with ironing machine and has two rails for guiding the seam and a device for folding over the seam legs. A disadvantage of this device is that the solution is technically complex and is used for the opening of the suture just a stream of air, which can not prevent them from tipping over on one side if the suture legs are not completely centric, and this device is not suitable for tubular curved workpieces. According to DE-AS 2528348 (D06F71 / 30) there is also a device for ironing preparation of.
