Abstract:
A system for forming a surface configuration, such as a neck and a flange, on a can body adjacent an open end thereof using a mandrel having an outer surface comprising generally cylindrical portions on each side of an annular recess which recess has a surface configuration corresponding to the neck and the flange to be formed. A resilient deformable object is located around the mandrel. A portion of a can body is placed between the mandrel and the resilient, deformable object which is then deformed so as to move a portion of the can body into conformation with the surface of the annular recess. At the same time, a force is applied to a portion of the portion of the can body being deformed to resist the movement thereof so that the portion of the can body in which the neck and flange is being formed is stretched and thinned as it is moved into conformation with the surface of the annular recess.
Abstract:
An overvarnish unit (20) for a can (28) decorator machine mounted on an adjustable frame (36, 38) which supports an adjustable applicator roll (34) for applying a coating material associated with a pre-spin wheel (33) for rotatable mandrels (26) and also supports an adjustable coating material meter roll (48) associated with an adjustable fountain means (50).

Abstract:
A system for trimming a can body (12) wherein a can body (12) is positioned within a cutting member (26) so that the cutting member (26) is at the location where the can body (12) is to be trimmed. A resilient, deformable object (30) is inserted into the can body (12) and positioned therein so that at least a portion thereof is located radially opposite portions of the can body (12) on each side of the cutting member. The resilient, deformable object is deformed so as to move the portion of the can body located between the cutting member and the open end of the can body in a radially outward direction so as to sever that portion (46) from the can body.
