Apparatus for deflashing hollow bodies of plastic material

Claim 1

Apparatus for successively removing plastic hollow bodies having a neck from a conveyor and deflashing the neck of such bodies, comprising, in combination: a. a movable support and a series of gripping elements arranged on said support for movement therewith along a path of transport going past a withdrawal point where each respective gripping element is in a position to grip externally the neck of a plastic body having a flash attached to its neck, to remove the body from the conveyor; b. fixed cutting means disposed for engaging the neck of the body along a portion of the path of transport beyond the withdrawal point; and c. movable means arranged for engaging externally the neck of the body as it is carried along the path of transport by its respective gripping element and approaches said cutting means, said movable means imparting to the body an independent movement of rotation about its longitudinal axis as the neck passes along said cutting means and in engagement therewith for cutting off the flash, said movable means being arranged for imparting to the body said movement of rotation independently from the movement along said path of transport imparted to said body by said support and said respective gripping element; and said support and said respective gripping element being arranged for imparting to the body said movement along said path of transport independently from said movement of rotation imparted to said body by said movable means.
