PRINCIPAL OF OPERATION
GENERAL
The strapping cycle can be divided into three
distinct operations:
a. Grip and tension
b. Weld, cut, and release
c. Feed
The following descriptions refer to Figures 15
through Figure 20. Note that both the
mechanical and the control functions of the micro
switches are described.
1. NEUTRAL POSITION. When the strap is
initially threaded through the machine, it
enters the head under the strap guide and
over roller ‘D’, between two sets of feed and
tension rollers and on through a slot in the
end gripper. It then passes beneath the
anvil, over the welding clamp and holding
gripper and out into the strap channel on the
left-hand side of the tabletop where the
operator has access to it.
