Definitions

• the invention relates to a flat knitting machine with at least one thread guide box which has a thread guide with a thread guide arm and a thread guide arm which can be pivoted out of its working position in the longitudinal direction ⁇ of the flat knitting machine
• a flat knitting machine with such a thread guide 10 is known for example from DE 33 10 723 AI.
• Different, contradicting demands are made of thread guides.
• the thread guide in the working position should be as firm and rigid as possible in the middle of the comb gap so that the needles can reliably grip the thread.
• the thread guide In the pivoted-out position, however, the thread guide, on the other hand, should be as movable as possible transversely to the direction of travel of the thread guide box, so that it can avoid other thread guides or can be easily pushed aside by them and no hooking is possible.
• Thread guides are known from DE 31 29 512 AI and DE 31 10 723 Cl, which are designed to be elastically resilient or in which the lower shaft part is articulated and resilient on
• the thread guide arms consisting of a resilient material can indeed avoid other thread guide arms or be displaced by them transversely to the direction of travel of the thread guide box, but they have the disadvantage that they
• the present invention is therefore based on the object of creating a flat knitting machine with a thread guide which fixes a defined, fixed position in the working position and optimal position with regard to the needle beds and the needles for securely grasping the thread by the needles and yet does not come into collision with other thread guides.
• this object is achieved according to the invention in that the thread guide in the working position has a smaller mobility transversely to the direction of travel of the thread guide box than in a position pivoted out of the working position.
• the thread guide is thus held in a rigid holding position during the working position, whereas when it is not in the working position, another thread guide occupies the space for the working position directly above the comb gap, transverse to the direction of travel of the thread guide box Despite the rigid position of the thread guide required for optimal knitting and possible with the features according to the invention during the working position, it is nevertheless possible to enable the thread guide to move transversely to the direction of travel of the thread guide box when the The thread guide is not in the working position, so that the space for the thread guide who is in the working position is free, or can easily displace the thread guides that are not in the working position, transversely to the direction of travel of the thread guide box. therefore not elastic thread feet to use, which have considerably greater advantages with regard to the knitting process than thread guides made of elastic material, which on the other hand nevertheless do not represent an obstacle for the other thread guides when they are not in the working position.
• the thread guide has an extension forming a thread guide guide element, which projects beyond the suspension of the thread guide on the thread guide box and projects into a guide slot.
• the thread guide is guided or restricted by means of the guide slot with respect to its mobility transversely to the direction of travel of the thread guide box.
• An advantageous embodiment of the inventive concept also consists in that the area of the guide slot for the thread guide guide element during the working position is narrower than the area of the guide slot for the thread guide guide element in the pivoted-out position. In this way it is possible in a simple manner to limit or fix the thread guide in the working position with regard to its mobility transversely to the direction of travel of the thread guide box, while its mobility in this direction can be kept greater when the position is pivoted out of the working position.
• a further advantageous development of the invention consists in that the width of the area of the thread guide slot is adjustable for the division of labor and / or for the position pivoted out of the working position.
• Figure 1 is a schematic representation of the inventive thread guide arrangement in a side view
• FIG. 2 seen the thread guide according to the invention and its guidance from above.
• the holder 3 is connected via connecting legs 5, 6 to the actual thread guide box 7 and can be pivoted via the legs 5, 6 from the working position in the direction of travel of the thread guide box 7 or in the opposite direction.
• the guide element 9 When the thread guide arm 1 is pivoted out of the working position, the guide element 9 is located in the slot area 11 or 12, in which the thread guide element 9 has greater freedom of movement transversely to the direction of travel of the thread guide box 7.
• the swiveled-out thread guide arm 1 drives past a thread guide arm which is in the working position, firstly, therefore, it is easy for the rotating holder to rotate and dodge.
• the side edges of the guide element 9 and / or projections 15, 16 and / or the screw 17 are chamfered.
• a screw 17 is provided in the embodiment shown, with which the slot width and thus the freedom of movement of the guide element 9 can be adjusted transversely to the direction of travel.
