39) Programmable Logic Controller
The Programmable Logic Controller (PLC) is used to control the machine's operating sequence.
40) Remote Demand Sensor
The Remote Demand Sensor is an optional infrared sensor, mounted on a downstream conveyor,
that detects cases, and thereby avoid jams by interrupting machine output.
41) Shock Absorber
Adjustable Shock Absorbers are used to cushion mechanical impacts at various machine
locations.
42) Sliding Frame
The Sliding Frame assembly slides over the main frame and changes position during adjustment
to fit the length of the case being processed.
43) Sliding Guard Doors
The Sliding Guard Doors provide easy access to the forming head and other assemblies. The
machine stops immediately when any door is opened during operation.
