Extruded material that has been sized and cooled enters the
cutter from the upstream side (See How the SC-5 Sure Cut
Works, Section 2, step 1). Typically, a puller is placed just
before the cutter; the puller pulls the extrudate through the
sizing and/or cooling tanks and feeds it into the cutter.
The positional servo motor, is direct coupled to the cutter
head, or an in-line planetary gear reducer that drives the cut-
ter head. The planetary gear reducer arrangement increases
cutting torque, improves servo motor efficiency, and offers
improved bearing load ratings.
The cutting knife, attached to the cutter head, is driven by
the servo motor (See How the SC-5 Sure Cut Works, Section
2, step 2). Two cutter bushings guide and support both the
extrudate and the cutting knife. The cutter head is mounted
directly to the in-line planetary gear reducer shaft using a B-
Loc coupling device, and may have as many as four optional
blade positions. See Installation and Removal of B-Loc,
Section 5.
Two types of cutting modes are available. On-demand cut-
ting modes (Timer, Encoder, Auto and Product) provide a
single rotation cut cycle. However, in continuous cutting
modes (Flywheel and Optional Follower) the cutting mecha-
nism rotates continuously.
The knife guard includes a stainless steel lower tray, which
can be used for blade lubrication. The upper knife guard
includes a clear polycarbonate window. This allows you to
watch the cutting blade during operation.
Cut pieces are collected or carried on to further processing
by an optional conveyor (See How the SC-5 Sure Cut Works,
Section 2, step 3).
