Abstract

751,742. Double-lift dobbies. STAUBLI, R., STAUBLI, H. H., and STAUBLI, O., [trading as STAUBLI & CO., GEB.]. Oct. 8, 1953 [Jan. 26, 1953], No. 27651/53. Class 142 (2). When the pair of draw knives 12, 13 of a double-lift open-shed dobby are at the inner end of their stroke, a bar 14 operated by a cam 22 presses all the hooks 9 on to the knife 13 ; any hooks that are required to engage the knife 12 are then rocked by levers 28 actuated by the pattern mechanism, which is as disclosed in Specification 751,728. The upper hooks 8 are similarly set by a bar 15 and levers 27. The invention is also applied to a double-lift closedshed dobby to press single-ended hooks on to each of the two alternately-operating knives, those not required to be moved being then lifted off by push needles controlled by the pattern mechanism. Specification 734,249 also is referred to.
