Clamping frame for stiok machines, especially stiok machines

The invention "relates to a clamping frame for embroidery machines, instes special for embroidery machines, with which a kind of repeat embroidery can be applied to finished goods. In one Such automatic embroidery machines have to put the goods in a frame for continuous, strip-shaped embroidery be clamped, which extends over several embroidery heads, whereby the distances between the individual heads are as follows are dimensioned so that the fields embroidered at the same time by the individual heads in one or more work stages touch one another or equidistant from each other. The clamping

the goods in such large embroidery frames causes difficulties, so far circular wood * known frames that stretch the flare smooth for the area of an embroidery head

The invention is based on the object of creating a clamping frame with which the to be embroidered It is quick and easy to stretch fabric in such a size that several embroidery heads at the same time embroider the hooped fabric. The handling should be so easy that also auxiliary staff get the job done in the shortest possible time; can do »

To achieve the object, the invention provides that tension springs are arranged on a frame part which can be pressed onto a tension ring on which the fabric to be embroidered is pretensioned are,. The frame part and the clamping ring each form a closed rectangle that is flat the embroidery areas of several embroidery heads. The clamping ring is expediently made of round material produced, the tension springs can be formed approximately U-shaped in cross section and extend over about

Figo 2 shows a section through one side of a Frame part according to line TI-II in Fig. 1.

The clamping frame consists of a frame part 1 and a clamping ring 2 ₀ On one side of the frame part 1 there are tension springs 3 which, in the embodiment shown, extend over almost all of the longitudinal sides 4, 4 'of the frame part 1. Expediently, as shown on a larger scale in FIG. 2 , the tension springs 3 have an approximately IJ-shaped cross-section, the base 5 is firmly connected to the frame part 1 . the legs 6,6 · are slightly exaggerated.

The clamping ring 2 is placed on a clamping table 7, ZUi ¹ fixation of its position, adjustment pins 8 are provided that go through the center of the narrow 9.9 'of the clamping ring 2 and are in the clamping table? are anchored. The clamping ring 2 is in its correct position between two recesses 10, 10 'into which the clamping rods 11, 11' are pressed. "

dor the rectangular clamping ring 2 is placed on the clamping table, observing the adjustment pins 8. Then the fabric 12, which extends beyond the recesses 10, 10 ', is written over it and the tension rods 11, 11 are lowered mechanically or pneumatically, for example by means of a foot switch, so that the fabric 12 runs in the longitudinal direction when it enters the recesses 10, 10' is pretensioned according to the double arrow. Manually or, for _e, via a second footswitch of the frame part 1 is then placed on the clamping ring 2, that is, the tension springs 3 on the longitudinal sides 4,4 'the position shown in FIG · 2 to finally be pushed onto the clamping ring 2, "reached The fabric 12 is also stretched and held in the transverse direction according to the double arrow 14. After the tension rods 11, 11 'have been loosened, the frame with the stretched fabric can be lifted and fed to the embroidery machine for embroidery of the fabric. The tension springs 3 also hold the fabric Tensioned in the longitudinal direction so that there is no inadmissible loosening after loosening the tension rods 11, 11

are appropriate.

The advantages achieved with the invention are in particular that the fabric to be ticked can be clamped quickly in a simple manner with a secure hold, the clamping surface is so large that several heads of the embroidery machine work on the clamped fabric at the same time can work. Since the clamping can be done at least haibau toma bisch, is a favorable way of working guaranteed The frame and the whole The jig is also cheap and easy to manufacture
