Roll Height Monitor
Assembly
The Roll Height Monitor assembly consists a horizontal beam which is secured
to the machine in place of the front squeegee ‘I’ beam. Two legs attached at
either end of the beam via THK linear bearings, house the laser light source and
receiver. Plastic wedges at the foot of each leg prevent damage to the stencil
whilst the print stroke is being carried out. The horizontal beam houses beam
extensions which can vary the beam’s length from 421mm to 575mm to
accommodate different size squeegees. Each extension is secured within the
beam by a cap headed bolt.
