Problems solved by technology

Since it cannot be ensured without problems that the filler is pressed evenly when the loop tool is inserted, there is also the risk that the loop tool must be reprocessed after the original production process for the They are oriented parallel to each other and aligned in the desired longitudinal direction

Embodiment Construction

[0015] The loop forming tool holder 1 has a plurality of sliders 2 which are held together by a plastic support 3 . To produce such a carrier, the slider 2 is inserted and fixed in a molding tool, not shown in detail. The desired final longitudinal orientation and parallelism of the slider 2 takes place here.

[0016] The forming mold has a hollow cavity whose shape corresponds to the shape of the support body 3 later. This hollow cavity is filled with highly soluble polyamide, which is charged into the forming mold with slight pressure, for example in the range of 3 to 40 bar, wherein preferably this pressure is in the lower part of said pressure range, That is in particular in the range from 3 to 10 bar.

[0017] Before the synthetic material is filled into the forming mould, it is heated to about 200°C. It is now possible to cool the synthetic material to a temperature of at most 60° C. or even at most 30° C. in less than 3 seconds, in particular about 2 seconds. Prefer...

Abstract

The method involves inserting an operating tool in a molding tool. The operating tool is impinged with a plastic, where the polyamide is used as plastic. The plastic is cooled from a temperature, in which the plastic is fluid, to a temperature of maximum 60 degree centigrade in a maximum of three seconds.

Description

technical field [0001] The invention relates to a method of manufacturing a loop forming tool holder, wherein the loop forming tool is placed in a forming die and loaded with synthetic material. Background technique [0002] The term "knit-forming tool" is used here as an abbreviation for those elements of a pointer loom, in particular a warp knitting machine, which are involved in forming the loops during the production of knitted goods. It therefore refers not only to the actual loop forming tools, such as knitting needles, slide bars, sliders and the like, but also to yarn guiding elements, such as yarn guide needles, comb sliders or the like. [0003] The loop forming tools in warp knitting machines are arranged side by side in large numbers. In order to make them easier to handle, several loop forming tools are combined in groups and fixed in brackets. These loop forming tool holders can then be installed in or on the needle bed of the warp knitting machine. [0004]...
