## Abstract

A device for crimping a plastically deforming metal pole shoe (1) around the end (2) of a cable that has been inserted into it. The device comprises an anvil (3), a die (4), a sensor (5), and a comparator (6). The shoe is placed on the anvil and the die is advanced toward it, deforming the shoe. The sensor emits a signal once the shoe has been deformed to the maximum, and the comparator compares the signal with a reference and emits either an "accept" signal or a "reject" signal. The "reject" signal emitted by the comparator actuates a cable-end trimmer that cuts part-way or all the way through the cable. Consequently, the device will always either acceptably crimp pole shoes to the ends of cables or reliably indicate defective connections.

## Claims

### Claim 1

An apparatus for crimping a plastically deforming metal pole shoe around the end of a cable that has been inserted into it, said apparatus comprising an anvil, a die, a sensor, and a comparator, wherein the shoe is placed on the anvil and the die is advanced toward it, deforming the shoe, and wherein the sensor emits a signal once the shoe has been deformed to the maximum, and the comparator compares the signal with a reference and emits either an "accept" signal or a "reject" signal, the improvement comprising a cable-end trimmer that cuts part-way or all the way through the cable in response to a "reject" signal emitted by the comparator, said crimping apparatus and said trimmer being arranged such that the cable end remains substantially stationary between a crimping operation and a subsequent cutting operation following a reject signal.

### Claim 2 (depends on 1)

The apparatus defined in claim 1, wherein the trimmer includes shears that partly or entirely remove the end of the cable.

### Claim 3 (depends on 1)

The apparatus defined in claim 1, wherein the trimmer includes at least one cutter.

### Claim 4 (depends on 1)

The apparatus defined in claim 1 wherein the trimmer includes at least one mechanism for removing the severed end of the cable.
