Towel Alignment Assembly (Wiggle Woggle)Moving further towards the front of the machine again, we come to the exposed wiggle-woggle cylinder and controls, shown here as it looks from the chute side of the console. This allows you better access for servicing the cylinder, as well as "fine tuning" the flow controls which set the speed of operation.

These flow controls allow better control of  the wiggle-woggle's operation than the system of regulators and quick-exhaust valves used on older machines.

Replacing the trouble-plagued air sensor and diaphragm-operated valve previously used to detect the towel edge is an optical proximity sensor and a solenoid valve. Cleaning requires only a wipe with a cloth on the photo eye. This is substantially easier than the rather risky art of disassembling the older valve, hoping to not damage any parts in the process.

The valve is housed with the rest of the solenoid valves for the machine, in the base of the operator's station, directly under the wiggle-woggle.

Rewind safety sensor w/reflectorShown here is something new; an optical safety sensor for the towel rewind, to help protect the operator's arm.

We have had reports of some operators wearing long-sleeve and loose shirts, blouses and coats while operating the CRT machine. This is a bad practice around any rotating machinery. One operator reportedly was injured when her sleeve was caught in a rewinding roll, twisting her wrist. While there is a large stop switch within easy reach of the rewind mandrill, we thought something more was needed.

This sensor (the black dot above the towel in this picture), when blocked, will disengage the clutch from the rewind mandrill. It is placed just above the diameter of a 55-yard towel, so as not to interfere with normal operations, but an arm in the wrong place will block it.

The inset shows the reflector for the photocell, mounted on the "third arm" assembly.
