Pneumatically removing beading from plastics weld - with tool fixed on piston rod and cylinder bearing against welded member

摘要

A pneumatically operated butt-removing tool comprises a piston in a cylinder, the piston rod being fitted with a peeling knife while the cylinder has an abutment or prop for fitting against the welded article while removing the butt. Typically, a V-shaped abutment fixed to the cylinder bears against the apex of a mitred joint while the piston rod pulls the peeling blade along the beading of the well.
