RJS 448 Quick Start Manual

The Model 448 Splice Press is employed in the steel
cord calendering process, and is used for splicing
the trailing ends of steel cords from a completed
creel run to the leading ends of cords from a newly
started creel run. The side opening feature allows
the splice press to be moved onto or off centerline
of calender while the steel cords are in place.
Splicing is done by use of uncured rubber strips to
bind the cords to each other by pressing the
rubber/cord assembly between the electrically
heated platens of the splice press.
The rubber strips become vulcanized and adhere to
the steel cords, thereby joining the many wires
sufficiently to allow the calendering operation to
continue.
The splice press is installed in the process line
between the forward end of the creel (after the
master organizing board, if one is used) and the
calender. One side of the splice press may be
opened so the splice press is manually moveable
between operating position (on centerline of
calender) and idle position. Sensors are activated
at operation or idle positions and may be used to
provide a signal at the calender PLC.
Each platen of the press is energized by turning on
separate switches located at the operator panel.
Each platen is individually controlled by its own
temperature controller, thermocouple sensed, and
in event of control failure, is protected from
overheating by a temperature limit switch which
shuts off power to the platen when the pre-set
temperature limit is reached.
limit is factory set at approximately 400°F (204°C),
and may be adjusted to a different value if
desired, but in no case should be set higher
than 480°F (250°C).
The guard is closed by holding the CLOSE Guard
button until it is completely closed. The Safety
Edge Guard System, if tripped when the guard is
moving, will stop movement until reset by push
button at operator panel.
The press is closed by pressing the CLOSE Platen
button at the operator panel. The press is unable

to close until the guard is completely closed. Two
hooks prevent deflection of frame when pressing.
The movement of the hooks and press are
interlocked.
Upon pressing the CLOSE Platen button, an
alarm light flashes until the press is completely
closed.
Automatic opening of the press is controlled by an
adjustable timer, which, when timed- out, causes
the press to open.
Apart from the timer, the press can be opened by
pressing the Platen OPEN button located at the
operator panel.
Customer may select right hand (RH) or left hand
(LH) machine, which indicates open end and
operator panel side.
A Safety Rope is located at the base of the Splice
Press.
The Splice Press may optionally be provided with
steel cord combs and magnetic cord retainers to
aid in the organizing of the cords over the platens.
