摘要

Improvements introduced in the mechanisms regulating the feeding of the frame in looms without lancer for narrow fabrics, characterized by arranging means forming puffs, a finger with an eyelet at one end for the weft thread and means for actuating said finger so that the The end moves in a closed curve through the shed and returns to the starting point, said actuating means comprising a finger guide which the latter traverses sliding, being able to oscillate it on a vertical axis, a crank with a journal which is attached to the other end of the finger for operation, said crank being provided with a rotating shaft on a vertical axis, and driving means for operating the shearing forming means and the crank shaft, a second guide eye in said finger at a point remote from said first eyelet, a thread guide element mounted on said crank, said guide having an opening whose edge is It is in contact with a weft yarn coming down from on said element and through said opening up to said second guide eye and through the first guide eye to the line of thrust of the pass of the fabric being knitted, such being the The shape of said opening means that the sum of the length of yarn from said edge to said second guide eye and the length of yarn from said first guide eye to the line of thrust of the pass increases at an essentially constant speed during each cycle. of operation of said finger after a change of warp draw.
