Trimming Open Top Drum Necks to a Flat Finish

After an open top drum leaves the accumulator machine, it is placed in this off-line rotary cutter, which trims the neck with rotating blades and automatic positioning so the mouth has a flat, consistent surface. A flat cut matters most when the drum must seal against a matching lid; bottom flash is removed separately. Because the cutter works off-line, trimming takes place outside the molding cycle.

The cutter is adjusted to the neck dimensions of each drum design, so the drum drawing and lid specification are the key inputs when it is added to a line. It is offered as auxiliary equipment for the open top drum machine rather than as a standalone product. Send the drum neck drawing and production volume to confirm the cutter fit and request a quotation.
