Harness frame angle connecting device

Abstract

The invention discloses a heald frame corner connecting device. In order to connect the heald plate (1) of the heald frame with the side support arm (2) of the heald frame, at least one guide surface is set on the heald plate (1). The guide surface extends at least approximately parallel to the longitudinal axis of the heald plate. In addition, the guide surface positively engages with at least one further guide surface on the projection (11) of the side support arm (2), which extends at least approximately parallel to the sheath plate or perpendicularly to the side support arm.

Description

technical field

[0001] Modern weaving machines place ever higher demands on the precision of the attachments. This is especially true for heald frames. Heald frames are subjected to high accelerations during weaving operations. In order to avoid additional loads, it is imperative, for example, to guide the heald frames with sufficient precision. However, an essential prerequisite for this is that the heald frame is manufactured with sufficient precision. In addition, they must be designed in such a way that for the drawing-in of the heddles, the side support arms can be easily disassembled and then reassembled with the original precision. The result of frequent product changes in weaving mills is that heddle boards and side support arms are mixed up. More precisely manufactured components can only solve this problem to a small extent because of the inevitable large variances in batch-to-batch manufacturing. Therefore, a new design solution is required. None of the hither...
