Deflecting beam for warp threads in a weaving machine

Claim 2

A deflecting beam for warp threads in a terry cloth loom comprising an elongated rigid non-rotatable support for disposition across the path of the warp threads and an elastically yieldable guide member secured to said support, said guide member having two longitudinal edges secured to said support and an elongated curved surface extending between said edges and across the path of the warp threads for sliding of the threads thereon, said surface being curved similarly to a cylindrical surface to at least partly surround said support, said guide member being made of leaf-spring like material for resiliently deforming under the influence of a variable tension in the threads in a direction away from said path coinciding with the angle bisector between the planes of an incoming group of the warp threads and an outgoing of the warp threads.

Claim 3

A deflecting beam as set forth in claim 1 wherein said support is tubular in cross-section.

Claim 4

A deflecting beam as set forth in claim 1 wherein said guide member is a metal strip at least partially surrounding said support and said surface is a cylindrical surface.

Claim 5

A deflecting beam as set forth in claim 1 further comprising an elastic damping element between said support and said guide member.

Claim 6

A deflecting beam as set forth in claim 4 wherein said support has at least one support surface facing said guide member and extending parallel thereto with said damping element therebetween.

Claim 7

A deflecting beam as set forth in claim 5 wherein said damping element is made of foam material.

Claim 8

A deflecting beam as set forth in claim 5 wherein said damping element is an inflatable hose.

Claim 9

A deflecting beam as set forth in claim 5 wherein said guide member is a closed tube of metal sheet material and said damping element is sandwiched between said support and said guide member.

Claim 10

In combination with a deflecting beam as set forth in claim 1, means for pivoting said support about an axis spaced to and parallel to the longitudinal axis of said support.

Claim 11

The combination as set forth in claim 9 which further includes means for prestressing said support in a second direction opposite said first direction.

Claim 12

In a loom for weaving terry cloth, said loom having means for directing pile warp threads through a predetermined path into a shed and means for beating up weft threads in said shed wile imparting tension to ground warps; a non-rotatable deflecting beam mounted in said loom and having a support for disposition across the path of the pile warp threads and an elastically yieldable guide member secured to said support, said guide member having two longitudinal edges secured to said support and an elongated curved surface made of leaf-spring like material extending between said edges and across said path of said pile warp threads for sliding of said pile wArp threads thereon, said beam surface being resiliently mounted in said loom to deform in a direction away from said path under the tension of said pile warp threads, said direction coinciding with the angle bisector between the planes of an incoming group of the pile warp threads and an outgoing group of the pile warp threads.

Claim 13

In a loom for weaving terry cloth, said loom having means for directing pile warp threads through a predetermined path into a shed and means for beating up weft threads in said shed wile imparting tension to ground warps; a non-rotatable deflecting beam mounted in said loom and having a support for disposition across the path of the pile warp threads and an elastically yieldable guide member secured to said support, said guide member having two longitudinal edges secured to said support and an elongated curved surface made of leaf-spring like material extending between said edges and across said path of said pile warp threads for sliding of said pile wArp threads thereon, said beam surface being resiliently mounted in said loom to deform in a direction away from said path under the tension of said pile warp threads, said direction coinciding with the angle bisector between the planes of an incoming group of the pile warp threads and an outgoing group of the pile warp threads.

Claim 14

In a loom for weaving terry cloth as set forth in claim 11 wherein said beam includes a deformable element between said support and said guide member.
