To in their dimensions constantly changing stenter frames

Workpieces with right-angled boundary lines

to be able to clamp quickly, wear with the well-known

th clamping frames, which can be assembled from individual parts, are the coupling slides, which are the guide rails set, two vertically intersecting guide slots. The associated clamping elements and clamping abutments also have a perpendicularly intersecting arrangement of the guide slot Clamping spindle axis. Through the coupling xo slides, the clamping elements and the Locking means or support bearings attached to clamping abutments will cause a displacement of the clamping frame forming parts prevented. Due to the constructively necessary distance between the intersecting The axes of the guide slot on the one hand and the clamping spindle on the other hand experience twisting during clamping of the tenter frame assembled according to the modular principle and thus at the same time of the workpiece to be clamped together. It must therefore also be on a stenter frame a torsion-resistant work table or a torsion-resistant frame.

To be independent of a torsion-resistant work table or a torsion-resistant frame to be, according to the invention, a frame composed of individual parts becomes another also assigned to frames composed of individual parts. This assignment is now constructive achieved in that the guide slots for receiving these two parallel frames in the coupling slides or articulated couplings are arranged in pairs at a certain distance from one another. This creates one out of two individual ones Frame formed torsion-resistant clamping frame, in which all clamping forces are within the range of the two individual frames enclosed space.

The drawing shows an exemplary embodiment for the one made up of an upper and a lower frame existing stenter frame according to the invention.

Fig. 1 shows a top view of the clamping frame that clamps several workpieces at the same time. The axes of the clamping spindles are perpendicular to the guide rails carrying the clamping elements.

A b b. 2 shows in cross section a coupling slide in which the intersecting guide slots are arranged in pairs.

According to the dimensions of the workpieces 1 shown in Fig. 1, the selection of the various applicants:

the length of the existing guide rails 2 for the upper frame and 2 'for the lower frame. These guide rails 2 and 2 'w ill be inserted into the existing pairs intersecting guide slots in the coupling slider 3 _ where it (not shown) by means of pegs are locked. The displaceable on the guide rails n tensioning elements 4 are displaceable Spa nnwider bearing 5 ge genüber. After inserting guide rails "inside the clamping frame, there is a further possibility of clamping additional workpieces, which can thus be clamped completely independently of one another. When using coupling pieces 6, the guide slots of which are inclined towards one another or can also be variably inclined towards one another , the workpiece can also be opened inclined boundary edges are clamped with a clamping element.

The coupling slide 3 shown in cross section in Fig. 2 shows the crossing guide slots in pairs at a certain distance from one another. The guide rails 2 form the upper frame, while the guide rails 2 'form the lower frame The clamping elements and the clamping abutments can be supported on a frame or on both frames at the same time
