Abstract
In an automatic splicing or welding installation comprising a wire holder (200) adapted to hold, in a pre-stripped state, wire segments (300) plugged in a given longitudinal alignment and in parallel extensions, as well as an automatic splicing or welding machine separate from the wire holder, a robotic arm is equipped with a robotic gripper for gripping pre-stripped wire segments in the wire holder, stripping the wire segments by forcibly withdrawing them from said wire holder, and bringing the stripped wire segments to the splicing or welding machine for splicing or welding them, while preserving the longitudinal alignment and the parallel extension of said wire segments. The gripper has a comb-like clamping wall structure (110a) comprising a series of parallel longitudinally extending and transversely spaced movable clamping walls (111), each pair of adjacent clamping walls forming a wire receiving passageway in which a wire segment can be gripped.
