摘要:
Device for supporting the temple and associated cover in a terry cloth loom with movable bench equipped with a selvedge device, of the type in which the support for said temple is mounted on a slide movable longitudinally in a direction parallel to the warp yarns and connected mechanically to the movable bench by means of a connecting rod. The cover of said temple is supported, independently of the temple support, by means of a pair of articulated rods, the first of said rods being connected to a part of the loom arranged above the cover and the second of said rods being connected to a second support integral with said slide and arranged downstream of the temple with respect to the forward direction of the fabric.

The present invention related to improvements in weft-carrying grippers for weft continuous feed weaving looms and in means for guiding their movement through the shed. The weft carrying grippers (1, 2) according to the invention, of the type wherein the grippers are made of metal and are driven in their back-and-forth movements through the shed by carbon-fibre and/or polyester straps exclusively guided from outside the shed are both characterised by a metal shoe (3, 4) integrated in said gripper and projecting from the bottom thereof, near the tip, to which it is radiussed and in that said shoe (3, 4) has a large central recess (7, 8), designed to host the ends (12, 13) of the driving strap (10, 11), which is narrower than the rest of the strap and thinner than the recess (7, 8) of the shoe. The respective means for guiding the movements through a loom shed of a pair of weft-carrying grippers (1, 2) as defined above, of the type wherein in the driving straps (10. 11) of said grippers there is a metal track covered in ceramic, is characterised in that said straps (10, 11) are quite larger than said grippers (1, 2), except near said grippers, and are guided by two double rows of hooks (19, 20) or by a pair of grooved guides placed outside the shed, and in that at least the parts (16, 17) placed outside the shed of said track have a large central longitudinal groove (21, 22) designed to host the shoe (3, 4) of said grippers (1, 2).

The present invention concerns a device and a method to control and adjust, in terry looms, the movements of the take-up roller and of the warp yarn guiding roller which cause the forming of terry loops, said device being of the type comprising a drive shaft (1) for transmission of a main rotary movement and an outlet lever (2) caused to rotate with an oscillating movement, between these two elements (1, 2) there being provided first mechanical members to determine the motion law and second mechanical members, in the form of a kinematic chain, to adjust the amplitude of said oscillating movement; said device also comprises actuating means apt to change the geometrical position of a movable hinge (10) of said kinematic chain, so that a specific transmission ratio and thus a given loop height may correspond to each of the geometrical positions taken up by said movable hinge (10).
