Abstract
A main wheel (11) is rotated to raise and lower the upper one of two horizontal feed rollers of a laminating machine. So that the pressure applied by the rollers is the same in successive operations a mark on an indexing wheel (14), which rotates with the main wheel (11), is brought into alignment with a mark on the casing (10) of the machine. The outer ring (14) of the indexing wheel is manually rotatable relative to its inner ring (13) but is held in frictional contact with the main wheel (11) by compression springs (17).
Claims5
A machine comprising a main wheel rotatable to adjust the pressure applied by another component of the machine to a workpiece and an indexing wheel in frictional engagement with the main wheel to rotate therewith but manually rotatable relative to the main wheel to bring an indexing mark on the indexing wheel into alignment with a mark on a stationary part of the machine adjacent the indexing wheel, wherein the indexing wheel is spring-biased into contact with the main wheel, the spring bias being sufficient to prevent accidental displacement of the indexing wheel while capable of being overcome when the indexing wheel is manually adjusted relative to the main wheel.
