Abstract

The invention relates to a device for changing the harness of a loom. It has two bearing columns (16) arranged on a chassis, two jibs (18) which can move vertically on the columns and horizontally extendible and a device (26) o the jibs (18) to transfer head frames. The head frame transfer device (26) comprises two spaced boundary plates 932) interconnected by at least one cross-member (28) and fitted with guide rails (30) for the head frames, and two spaced bearers (34) on a transverse support (22) connected to the boundary plates 932) and which can pivot in relation to the transverse support (22) to accept and transfer the head frames. In order to adapt the article changer to different weave widths, the distance between the boundary plates (32) can b adjusted by hand or by a motor. To this end, the cross-members (28) and the transfers support (22) consist of two simultaneously actuated teles copic sections (28', 28"; 22', 22").

Device for transferring the harness frame of a loom, the loom including at least two bearing columns (16) provided on a chassis (10), a vertically moveable jib (18) on each of said bearing columns (16), and means for vertically moving said jibs, the device (26) for transfer of harness frames provided on said jibs, said transfer device (26) including:

two boundary plates (32) spaced apart from each other,
at least one cross-member (28) connecting said boundary plates,
guide rails (30) provided on said boundary plates for guiding said harness frame, and
at least two bearers (34) for receiving and transferring the harness frame, said bearers provided on a transverse support (22) and connected to the boundary plates and pivot with respect to the transverse support (22),
wherein the distance between the boundary plates (32) is adjustable via motor means, wherein the at least one cross-member (28) and the transverse support (22) respectively comprise at least two simultaneously telescoping parts (28', 28";
22', 22"), and wherein a synchronous or parallel drive means is provided between the boundary plates (32) and the transverse support (22) which drive means includes a lengthwise adjustable synchronization shaft (36) which extends through the transverse support (22) and which is adjustable in length together with the transverse support (22).
