Problems solved by technology

Due to the curved and elastic design of the hook, the hook is unstable in the longitudinal direction of the steel lifter, with the result that a reliable interlocking of the drive with the blocking device cannot be ensured
This can lead to imprecise operation of the yarn control device, reduced rotation rates, and weaving errors in the final fabric produced

Embodiment Construction

[0019] figure 1 A schematic illustration of a yarn control device such as is particularly suitable as a shedding device for a knitting machine is shown. In this thread control device, warp threads 2 fed via warp beams 8 are led to sheds 6 by means of drives 4 designed as heddles. After each shed change, the weft thread 10 is fed into the shed 6 and beaten at the selvedge 12 in order to obtain a fabric, which is taken up via the take-up roller 16 .

[0020] The yarn control device comprises drives 4 which have loops through which warp threads 2 are guided. The drives 4 are prestressed into the basic position by means of a spring 20 in one direction, for example downwards here. An oscillating lifting device 22 with a lifting knife 24 engages the drive 4 via a stop 26 and moves the latter up and down in rhythm with the lifting device 22 until the drive is stopped in a high position by means of a blocking device 28 . The blocking means comprise a control means 30 in the form of...

Abstract

The invention discloses a cordless yarn control device for selectively controlling the oscillating movement of a yarn (2) transverse to its longitudinal direction, in particular of the warp yarn (2) associated with a shedding device of a mechanical knitting machine. Sports. The yarn control device of the present invention is provided with at least one lifting device (22) that can be driven in an oscillating manner; and at least one drive mechanism (4) for the yarn (2). Furthermore, at least one locking device (28) is provided, said locking device comprising a control device (30) drivable by means of a driver (34) in order to selectively engage the drive mechanism (4) with the lifting device (22) . In order to improve performance and service life, and to reduce noise radiation, the yarn control device includes a damper (40) connecting the various parts (4a, 4b) of the two-part drive mechanism.

Description

technical field [0001] The invention relates to a cordless yarn control device according to the preamble of claim 1 . Background technique [0002] A cordless thread conrtol device of the initially mentioned type is known from eg GB 1219012A. A drive for the yarn designed as a steel lifter with a hook on its end facing the blocking device, by means of which the steel lifter can optionally be interlocked to the blocking device . The hook has an arcuate configuration in order to impart elasticity to the end of the driver for damping the interlocking of the hook and the blocking means. Due to the curved and elastic design of the hook, the hook is unstable in the longitudinal direction of the steel lifter, with the result that a reliable interlocking of the driver with the blocking device cannot be ensured. This can lead to imprecise operation of the yarn control devices, reduced rotation rates, and weaving errors in the final produced cloth web. Contents of the invention ...
