Device to alter the distance between the frame stave of a heald frame and the heald carrying rod held by rod holders on the frame stave

摘要

On the frame stave (1) of a heald frame there is by means of a rod holder (5) a heald carrying rod (6) arranged in such a way that its distance to the frame staves (1) can be changed. An eccentric ring (10) with a polygon shaped outer circumference engages for this purpose in a rectangularly shaped recess (7) provided in the rod holder (5). The eccentric ring (10) is securely connected against free rotation with an intermediate element consisting of a concentric ring (11) and a center core (12) which is securely connected against free rotation. The center core together with its concentric ring (11) is seated in a bore provided in the frame stave (1) by means of each one appropriate configured shoulder (21) and the external toothing (14) configured at the ring (11) is between those shoulders and its outside diameter is larger than the diameter of bore (20) resulting that the teeth of the outer toothing (14) engages securely into the counter part of the eccentric ring (10) and the teeth profiles lodge in the hollow space touching the inside walls for the purpose of securing a displacement of the element in axial direction. The concentric ring (11) possesses a partition slit (22) and for that reason it can be inserted from outside into the bore in the frame stave (1) and brought into appropriate position, after the rod holder (5) together with the eccentrical ring (10) was inserted through an opening (4) provided at the frame stave (1). A center core (12) is inserted and securely kept against free rotation in the concentric ring (11) and the complete unit can be rotated resulting in the rotation of the eccentric ring (10) and as a result the rod holder (5) with the heald carrying rod (6) can be moved in relation to the frame stave (1).
