ABSTRACT:
In order to thread a frangible strip material such as aluminium foil through a rolling mill stand, the leading end of the strip at the upstream side of the stand is attached over its width to a transverse threading device. The threading device is mechanically propelled through the stand to a downstream coiler location, where the leading end is detached and coupled to the coiler. The threading device either may be drawn through the stand by means of a leader strip which is normally located at the downstream side but which can be passed through the stand and attached to the threading device, or may be pushed by semi-rigid chains which are normally located at the upstream side and which carry the threading device.
