RJS 448 User 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 o 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
suciently to allow the calendering operaon to
connue.
The splice press is installed in the process line
between the forward end of the creel (aer 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 operang posion (on centerline of
calender) and idle posion. Sensors are acvated
at operaon or idle posions 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
overheang by a temperature limit switch which
shuts o power to the platen when the pre-set
temperature limit is reached. The temperature
limit is factory set at approximately 400°F (204°C),
and may be adjusted to a dierent 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
buon unl it is completely closed. The Safety
Edge Guard System, if tripped when the guard is
moving, will stop movement unl reset by push
buon at operator panel.
The press is closed by pressing the CLOSE Platen
buon at the operator panel. The press is unable
to close unl the guard is completely closed. Two
hooks prevent deecon of frame when pressing.
The movement of the hooks and press are
interlocked.
Upon pressing the CLOSE Platen buon, an
alarm light ashes unl the press is completely
closed.
Automac opening of the press is controlled by an
adjustable mer, which, when med- out, causes
the press to open.
Apart from the mer, the press can be opened by
pressing the Platen OPEN buon located at the
operator panel.
Customer may select right hand (RH) or le 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 oponally be provided with
steel cord combs and magnec cord retainers to
aid in the organizing of the cords over the platens.
