Abstract
In a wire drawing machine having at least one station with upper and lower blocks and an associated spinner carrying a transfer sheave, the blocks and spinner being rotatable relative to each other about a common axis defined by a drive shaft to which the lower block is drivingly connected, the improvement comprising controllably shifting the spinner axially on the drive shaft into and out of frictional contact with the lower block.
Claims7
In a wire drawing machine having at least one station with a rotatably driven shaft on which are arranged upper and lower blocks and an associated spinner carrying a transfer sheave, the upper block and spinner being rotatable relative to each other on said shaft and the lower block being driven by said shaft to draw wire through a die, the thus drawn wire being temporarily accumulated as a plurality of windings on the driven lower block before passing via the transfer sheave to the upper block where the wire is again temporarily accumulated as a plurality of windings before leaving the station, the improvement comprising:
- means for mounting the spinner for axial movement on said shaft in relation to the lower block;
- separating means for yieldably urging the spinner axially away from the lower block to maintain a spacing therebetween;
- and control means acting in opposition to the separating means to axially urge the spinner into contact with the lower block, thereby causing the spinner to be frictionally driven by the lower block.

- means for permitting the spinner and the upper block to shift axially along said shaft in relation to said lower block;
- resilient separating means for urging the spinner away from the lower block to yieldably maintain a spacing therebetween;
- and remotely operable control means acting through said upper block in opposition to said separating means to urge the spinner into frictional contact with the lower block, thereby causing the spinner to be frictionally driven by the lower block.
