1,228,998. Corrugating; shearing. B. G. SOAR. 22 May, 1969 [8 Aug., 1968], No. 37889/68. Headings B3E and B3W. [Also in Division F2] A machine for crimping wire for use in the manufacture of woven wire baskets comprises two meshed crimping wheels 3, 4 each carried by a pair of parallel shafts coupled with constant angular relationship to a common drive source one of said shafts movable radially with respect to the other shaft whilst remaining parallel thereto, the radially movable shaft being connected to the common drive source by a variable coupling of constant angular velocity. The upper crimping wheel 3 is vertically adjustable, by a knurled hand wheel 11 and one end of the shaft 18 on which the wheel 3 is mounted carries a collar 19 of an Oldham-type coupling (Division F2). The other collar 20 of the coupling is mounted on a shaft 21 carrying a pinion 23 meshing with a pinion 17 on the shaft 14 of the lower crimping wheel 4. A pinion 24 on the shaft 14 is driven by an electric motor 29 through a gear-box 28. Also on the shaft 14 is mounted a toothed master disc 31 which cooperates with an electronic tooth-sensing device 32 connected to an electronic counting device 34 and controls an electrically operable clutch 35 which operates a rotary cutting device 39, 40 to sever a predetermined length of the crimped wire. A stop holds the cutter drums in their rest position and is released automatically by the counter 34 at the same time as the clutch 35 is actuated. Alternatively a reciprocating shear or scissor mechanism travelling with the wire is used.
