MAJOR COMPONENTS
In Fig 1.thru 4 the major components of the
machine and the strapping head are
shown in detail.
A detailed description of additional
systems and specific components follows.
STRAP DISPENSER:
The dispenser supplies strapping material
to the strapping head .It is located inside
the cabinet on the lower left-hand side. A
friction brake is provided to limit over-run of
strap.
1. GRIP-The grip holds the lead end of the
strap beneath the anvil while the
remainder of the strap is being tension
around the package.
2.STRAP FEED AND TENSION-Both feed
and tension are achieved by two sets of
gear rollers powered by an electric
motor by means of a drive-belt and
slip-clutch system.
An operator controlled adjustable timer
controls the duration of strap feed. When
the set time for feeding is up, the timer
stops feeding strap. If additional feed is
required beyond that determined by the
timer setting, jog feed will be facilitated
by pushing the “Jog” feed button on the
operator’s control panel.
3.WELDING AND CUT-OFF-Welding of
the strap ends and cutting of the strap
supply are facilitated in this process.
4.PACKAGE REKEASE-After a short
weld-cool period (necessary to avoid
welded ends from popping open) the
package is released.
HOT KNIFE. The “Hot Knife” is
centrally located at the front of the
strapping head Movement of the
knife is controlled by a cam.
ELECTRICAL SYSTEM, An all
electrical system using solid state
technology supplies continual power
supply to the electrical components
within the machine. Using simple to
insert circuit boards provides for
safe and fast maintenance free
operation.
OPERATOR CONTROLS. The
Electrical Control Panel consists of
the “Main Power ON-OFF Switch”
“Feed Length Timer,” “Reset Switch”
and “Feed Length Switch” (Jog
Feed).
INTRODUCTION
This manual contains safety,
operating, and maintenance
instructions for the Semiautomatic
Power Strapping Machine. This

to 15mm) wide. The strap ends are
joined by means of “hot-knife”
welding process.
(Note:) The above mentioned functiond:1,3
and 4 are driven by a cam shaft coupled to
