1 - 6 Watkiss Automatic SpineMaster Service Manual - Edited 17/06/04
Introduction • Product Overview
The Clamp Optical Sensor detects the presence of the booklet, and activates
the Carriage Motor.
After a preset pause, the Clutch on the Drive Motor is activated, which allows
the Drive Shaft to make one complete revolution. This drives the Bolster to-
wards the Anvil (the rotary motion of the Motor is converted to this lateral
movement via two Cam Links on the chain-driven Drive Shaft). The Bolster
and Anvil clamp the booklet in place, just above the spine (see Figure 1:6).
Collectively the Bolster and Anvil are known as the ‘Clamp’.
The spine is formed by the Roller Follower which is transported on the Car-
riage (see Figure 1:6). This Carriage is driven by the Transverse Chain, pow-
ered by the 24V Motor. With the booklet firmly clamped, the Carriage travels
the length of the spine, and the Roller Follower presses the spine into the re-
quired square profile. For this to happen, the Stop must first be moved out of
the way, so the Carriage is fitted with vertical Cam Rollers that push the Stop
rearwards.
When the Carriage reaches the end of the Carriage Guide, it activates either
the LH or RH Limit Sensor. There is one of these sensors at either end of the
Guide, because the Carriage can travel in both directions. For more informa-
tion on this see Section 1.6.4.
WARNING If for any reason the Carriage is stopped before it reaches one of the Limit
Sensors, it will move towards either the RH or LH Limit Sensor once power is
