d) Film Welding and Cutting - Permanently heated bar with PID Electronic
temperature control. Quickly removable, welding-cutting tip ease of
maintenance. Welding bar height is adjustable with a quick-set clamp.
e) Film Feed - Centre shaft, film roll support with gravity feed, controlled by
multiloop film accumulators. AC motor driven twin roller cradle type support is
optional.
f) Film Loading - film rolls are mounted right at front of machine to facilitate ease
of loading and minimize risk of operator injury.
g) Transfer Surfaces - Collating table is lined with UHMW polyethylene to
minimize friction and wear. Outfeed table and slide are stainless steel.
h) Safety - Low pressure welding bar descent with electrical trip, two Stop
Buttons. Electrically interlocked transparent doors around collation table area.
For Tunnel
a) Control System - simple Relay/contactor circuit with some electronic control
b) Conveyor Drive - gear motor. fixed or variable speed depending on application
c) Conveyor Belt - stainless steel mesh for general purpose tunnels. STH uses
heavy duty chain with flat bars for product conveying.
d) Air Circulation - two or Four centrifugal force impellers are used to provide
symmetrical air pattern.
e) Heating - finned type air heating elements controlled by PID Electronic
Temperature control unit.
f) Outfeed accumulation conveyor - free running roller type accumulation
conveyor is provided.
g) Safety - the machine is well guarded. Where possible standard stainless
conveyor of small pitch is used. Two stop buttons are provided on either side of
the tunnel for emergency use.
