Embodiment Construction

[0019] The weaving loom M partially shown in FIG. 1 can weave a plurality of ribbons R in parallel by intersecting warp yarns 1 and weft yarns 2 with each other. For each ribbon R, the weft threads are spaced more or less apart from each other to form a shed F, which can be obtained, for example, by means of a Jacquard-type mechanism , which is known per se and is not shown.

[0020] For each ribbon, the weft thread 2 is supplied by a spool (not shown) and is guided into the shed F by means of a sickle 4 which is driven by a reciprocating rotational movement F about a substantially vertical axis X-X' 1 driven by. The weft thread 2 passes through an eyelet 41 made near the free end 42 of the sickle 4, in which the mechanism for driving the shaft XX' is not shown for clarity of the drawing.

[0021] In order to keep the weft thread at the level of the selvedge closest to the observer in Fig. 1, associated with each sickle 4 is a knitting needle 5 driven by a back and forth rec...

Abstract

A device for driving crochet needles of a reaphook type braiding machine is provided, which comprises a rotary electrical actuator (6), the output shaft (7) of the rotary electrical actuator (6) is connected with a plurality of crochet needles (5)in dynamic linkage through devices (8,9) used for converting the rotation (F5) to translation (F2).

Description

technical field [0001] The invention relates to a device for driving the knitting needles of a sickle-type knitting loom, and also to a knitting loom equipped with the device. Background technique [0002] In the field of sickle-type weaving looms, in order to form the selvedges of fabrics or ribbons during the manufacturing process, one usually uses so-called knitting needles, which work in a reciprocating motion synchronously with the movement of the sickle, which is for hooking The weft yarn carried by the sickle is woven into a web with the previous weft yarn. Such knitting needles are usually provided with a latch and are controlled by a device combining cams and linkages, which must be precisely adjusted for the purpose of fixing the extreme positions of the amplitude and travel of these knitting needles. These drive and control devices are very complex and relatively unreliable. In addition, they are expensive and require long and careful adjustments, so that satisf...
