Abstract
An arrangement comprises heald frames, linear drives and coupling apparatus that are collected together in groups. The linear drives of each group are arranged in a staggered fashion and form a drive unit. The coupling apparatus are executed in such a manner that the staggering within a group can be selected. With this arrangement an ideal ratio of drive power to required space is achieved. In addition, the elements forming a group are interchangeable.
Claims14
An arrangement for the formation of a shed, the arrangement comprising heald frames which are arranged parallel to and spaced with respect to one another and which contain two heald slide bars and healds arranged between them, linear drives in order to move the heald flames up and down, and coupling means in order to releasably connect the heald frames to the linear drives, wherein the linear drives at the two heald slide bars are arranged at fixed spatial positions in their longitudinal extent and at a distance from one another on the side of the heald slide bars remote from the healds;
- and in that the heald frames, the coupling means as well as the linear drives in each case are positioned together in groups, with the linear drives being arranged transversely to the longitudinal extent of the heald frames in a staggered fashion.
A weaving machine with a pack of heald frames, the weaving machine including an arrangement for the formation of a shed, the arrangement comprising heald frames which are arranged parallel to and spaced with respect to one another and which contain two heald slide bars and healds arranged between them, linear drives in order to move the heald frames up and down, and coupling means in order to releasably connect the heald frames to the linear drives, wherein the linear drives at the two heald slide bars are arranged at fixed spatial positions in their longitudinal extent and at a distance from one another on the side of the heald slide bars remote from the healds;
- and in that the heald frames, the coupling means as well as the linear drives in each case are positioned together in groups, with the linear drives being arranged transversely to the longitudinal extent of the heald frames in a staggered fashion, wherein the weaving machine includes means for receiving a pack of frames.
