ABSTRACT:
A tie gun for applying a flexible tie around a roll or bundle, said tie having an apertured head through which the tail of the tie, after looping around the roll or bundle, is threaded, tensioned and locked in position, the gun incorporating an indexing means in the form of a rotary drum which advances successive ties, tail forward, into the path of a push rod driven by a trigger actuated, pneumatically operated piston so that said push rod performs a rearward stroke during the second part of an operating cycle and in so doing indexes the tie feed drum and simultaneously turns the buckle of an advanced tie into a tail receiving position, thus completing loading of the gun in readiness for the next operating cycle during the first part of which the push rod moves forwardly to push the tail around the roll or bundle to be tied back through the pre-orientated buckle ready for tensioning and locking.
