VALVE-OPERATED JOINER

Single motor and pump with valves to operate the joiner
Hydraulic valve circuit has three settings

Loop setting - oil is circulated from reservoir through the pump and back to reservoir
Close setting - oil is directed to the cylinders to close the joiner/die
Open setting - oil is pumped out of the cylinders back to the reservoir to open the joiner/die

Electrical demands are reduced
- Inrush current during plug reversing is eliminated
- Amperage peaks are reduced
- Load to the motor starter is reduced
A soft start can be used for the first few seconds of the cycle. Standard NEMA or IEC motors are used
Smaller breakers and line wires can be utilized
The press can be jogged without adding stress to the motor
A timer shuts the motor off a few seconds after the stitch is made, thereby reducing energy use
A PLC interface is available

OPTIONAL REVERSE DRIVE JOINER

The simple robust drive that we have used for over 50 years! Only electric power is required to operate the Standard Joiner.

A single motor drives dual pumps to operate the joiner.

When the stitching cycle is initiated, the motor drives pumps that pump oil into the cylinders and the die closes.
Through precise position sensing, the electric motor is reversed and the pumps now pump oil out of the cylinders. This reverses the direction of the RAM opening the die.

Simple, time-proven design
The drive has very few basic parts; a motor and two pumps
The motor only runs while the stitch is being made. The rest of the time it is off and consumes no energy
The drive is easy to understand and operate
A dual shaft NEMA motor is used
A PLC interface is available
