## CPC

- B21F 23/00: Feeding wire in wire-working machines or apparatus
- B21F: WORKING OR PROCESSING OF METAL WIRE (rolling of metal wire B21B1/16; by drawing, auxiliary operations used in connection with metal-working without essentially removing material B21C)

## Abstract

The invention relates to a wire feed station of a wire shaping machine, said station including grooved rollers functioning in pairs and rotating in reverse directions with respect to each other. The wire is clamped between said rollers by these moving closer to one another. Both rollers of the same pair of driving rollers are supported at the front of the same bearing block unit, said bearing block being elastically deformable to absorb a relative movement of the rollers. Preferably, said bearing block also supports an endless transmission screw on which are engaged a couple of transmission wheels coaxial with the driving rollers which they drive into rotation. More particularly, a bearing block is deformed so that a relative movement of the rollers results in a rotation-deformation of the bearing block about the transmission screw axis.

## Claims

### Claim 1

A wire feed station for a wire shaping machine, the wire feed station comprising:
a plurality of pairs of grooved rollers in which the grooved rollers of each pair rotate in opposite directions, each pair of grooved rollers suitable for clamping wire between the rollers by moving the rollers toward each other;
a plurality of bearing blocks respectively supporting said plurality of pairs of grooved rollers at a front thereof, each bearing block of said plurality of bearing blocks being elastically deformable so as to absorb a relative movement of the respective pair of grooved rollers on the bearing block;
a plurality of pairs of transmission wheels arranged coaxially and respectively with the pair of grooved rollers on said plurality of bearing blocks, the transmission wheels suitable for driving the grooved rollers in rotation; and
a transmission screw supported by the bearing block, said transmission screw engaged with the pair of transmission wheels, the bearing block being deformable such that a relative movement of the rollers results in a rotational deformation of the bearing block about an axis of said transmission screw.

### Claim 2 (depends on 1)

The wire feed station of claim 1, said bearing block having a horizontal planar slot opening at a front of the bearing block, said planar slot extending rearwardly so as to open at a rearward end to a circular hole, said circular hole opening laterally to either side of the bearing block.

### Claim 3 (depends on 1)

The wire feed station of claim 1, further comprising:
a spreader beam supported by a bar and moved by a stretching screw, said spreader beam affixed to the bearing block.

### Claim 4 (depends on 1)

The wire feed station of claim 1, said plurality of bearing blocks having units thereof coupled together.
