Appl. No.:

12/236298

Inventors:

George A. Holmes - West Chicago IL, US
Tadeusz Rybka - Streamwood IL, US

Assignee:

C.D.L. Technology, Inc. - Addison IL

International Classification:

A21C 1/06
B21D 35/00

US Classification:

366 85, 72341

Abstract:

A continuous bi-metallic twin bore barrel is produced by forming first and second single bore barrels, centrifugally lining the bores of the single bore barrels with a bi-metallic liner, heating the single bore barrels to harden the linings, fastening each single bore barrel into a barrel machining jig, and cutting each single bore barrel along its length to expose its bore. The barrel machining jigs are fastened together such that two single bore barrels are positioned adjacent and in contact with one another and their bores are in communication with one another. The two single bore barrels are seal welded together to form a twin bore barrel. The twin bore barrel is removed from the jigs and clamped along its length.

Abstract:

An underwater pelletizer for cutting extruded plastic into a flow of liquid is disclosed. The pelletizer includes a cutter hub () carrying at least one cutter blade (), a cutter shaft () for rotationally driving the cutter hub, and a flexible torque converter () for connecting a motor to the cutter hub. In one embodiment, the torque converter has a first set of bushings () that is fastened to a face () of the cutter hub and a second set of bushings that is fastened to a face () of the cutter shaft. The disclosed pelletizer has a shaft extension () configured to engage a motor shaft, the shaft extension having an outer diameter having formed thereon a splined portion () and first () and second () sealing surfaces. A disclosed motor adaptor () has a seal surface (). A water chamber plate () may also have a seal surface (). A first mechanical seal () is illustratively configured to engage the first seal surface () of the shaft extension and the seal surface () of the motor adaptor. A second mechanical seal () is illustratively configured to engage the second seal surface () of the shaft extension and the seal surface () of the water chamber plate. Furthermore, a cutter shaft () has a splined bore () formed therein for engaging the splined portion () of the shaft extension.
