To grasp the two longitudinal edges of the material webs to be tensioned, the tensioning chains for fabric tensioning machines combined tensioning clamps known in various designs. In such Clamps, for example, the needle part is pivotably connected to the clamping part and can be pivoted be brought out of the area of the web. This known design has the disadvantage that. the Needle part hinders the drying of the web during use of the clamping part. The to Other versions of combined tensioning clamps with foldable or Needle parts that can be swiveled into the working position as required.

Combined tensioning clamps are also known in which the clamping part and the needle part are connected form rigid clamping body which is pivotable about an axis that optionally the clamping part or the needle part can be brought into the working position. These combined tension clamps are like that known both with perpendicular to the web as well as with axes lying transversely to its running direction. They have the disadvantage that a large swivel angle is required, which is the · operation, · the engagement and determination of the clip body in its two »5 working positions made difficult and the design of the Clamp complicated. It also makes it difficult for these combined tensioning clips to remove them its guide parts, which are combined to form an articulated chain [for the purpose of cleaning and repair separate. Since also at. this well-known Spanhklupperi clamping part and needle part are arranged to each other that their rotation must be done by 180 ° in order to "move them from one to the other other working position to 'transfer, these clamps also have a greater installation height, the their use is restricted by the fact that the drying nozzles are not close enough to the material web can be introduced.

In the case of the combined 'tensioning clips of the invention, the clip body forming the clamping part and needle part can be pivoted about an axis parallel to the web of material and in its running direction in both working positions. The surface of the ".needle bar is at an angle of less than 9 °, preferably at an angle γόη 75 ° to the clamping table _i, whereby a 'smaller installation height of this clamping clip' is achieved 'and the drying nozzles • closer and at the same distance on both sides The pivoting of the clip body into its two working positions allows the valve body to be repositioned and locked in its two combined tensioning clip for tissue tensioning machines due to the smaller angle of rotation of preferably 75 °

Perform work positions in a very simple way with the help of a resilient rocker arm. Through the novel storage of the pivotable clip body and its engagement in the two working positions by a spring action Rocker arm it has become possible that the axis of the clip body in open bearing hooks of the guide part is a storage that allows the. Clip body without dismantling others Remove clip parts from its storage and separate from its guide part. This is particularly useful for cleaning and repairs on the clip body; because the guide parts connected to form an articulated chain are cut off by sewing of the clip body is not affected in any way.

The chain pins are held in place by a locking plate, which is useful as the support bearing for the The spring link of the toggle lever carries the locking plate is held in place by a spring-loaded slide valve, whose. Nose engages in the guide part

It is useful to increase the tensile force of the tensioned 'web of the connecting line of the tensioning point, Let the middle of the adfese of the clip body and middle of the guide part act and accordingly Clamping table and needle bar on the clip body can be changed - "/ -...

The new type of pivoting of the clip body around a parallel to and in the web. Running direction lying axis also has the advantage that when the needle part is used, the position of the Kluppen.körpers determined by a stop on its guide part and against the pressure of the pin brushes

is secured. When using the clamping part in this arrangement of the axis, the position of the clip body is also determined by a stop on its guide part. . In the drawing, the new clamp is shown in one embodiment. It shows Fig. 1 the combined tensioning clip in a side view with the clamping part in the working position, Figs. 2 and 3 the combined tensioning clip in the position according to Fig. 1 in the basic view and front view, Fig. 4 the combined tensioning clip in a side view with the needle part in the working position, Fig. 5 the resilient toggle lever with locking plate of the chain pins and locking slide with nose in side view. The rigid clip body 1 has the clamping table 2 with Kläppchen3 and the needle table 4 with needle bar 5. The clip body is mounted with the axis 6 in open hooks 7 of the guide part 8; it has ao a rear arm 9 which, together with the spring member 12 movably supported on the abutment 17 of the locking plate 10 of the chain pins 11, forms a knee joint. The locking plate of the chain pins has a spring-loaded locking slide 13 with a nose 14 (Fig. 5), which engages in the guide part and prevents the locking plate of the chain pin and thus the chain pin itself from falling out. When pivoting the clip. body in one or the other working position, this knee joint is moved beyond its dead center and pushes both the clamping part and the needle part into their working positions until corresponding parts of the clip body come to rest against stops 15 and 16 of the guide part 8 and thereby the clip body in its is held in both working positions by resilient notches. The effect of the axis of the clip body forming the clamping part and the needle part, which is parallel to the web of material and in its running direction, comes into play to the same extent when the combined clamping clip deviates in details from the clamping clip shown and described in the drawing. This relates e.g. B. on the resilient engagement of the clip body in its two working positions and the storage of the axis of the clip body in open hooks of the guide part; a storage of the axle in closed bearing hooks would only impair the easy separability of the clip body from its guide part, but not the other described advantages of the combined tensioning clip forming the subject of the invention. Patent claims: 1. Combined tensioning clamp for fabric tensioning machines, with which clamping part and needle part form a rigid, changeable clip body, characterized in that the clamping part (2,3) and the needle part (4, 5) forming clip body (1) around a parallel to the web and in the axis (6) lying in the direction of travel can be pivoted and locked in its two working positions. is cash. 2.
