Abstract
Hook construction for the harness pull of a double-lift open-shed Jacquard machine. For use in a Jacquard machine, as aforesaid, there is provided a construction for a resilient harness pull hook, same having relatively resilient characteristics in the upper portion thereof and relatively rigid characteristics in the lower portion thereof. Said construction may be obtained by appropriate treatment of the hooks during the process of manufacture of same or said characteristics may be obtained by fastening, as by welding, two separate components, one thereof being relatively resilient and the other thereof being relatively rigid. An offset may be advantageously provided in the resilient portion of such hooks for improving the guidance thereof.
Claims9
A single-shank, resiliently flexible, hook for use in a double-lift, open-shed Jacquard machine, said hook having a body part with two vertically spaced connecting noses and a support nose mounted thereon, said support nose being arranged on the hook below said two connecting noses and a spring portion extending away from said support nose in the form of a resilient extension which is bent backward at 180.degree. relative to said body part, comprising the improvement wherein said body part of said hook has a first zone (I) between said two connecting noses, a second zone (II) located between the lower one of said two connecting noses and said support nose and an immediate third zone between said lower one of said two connecting noses and said second zone (II), said body part in said third zone being more resilient than is said body part in said second zone (II).
