ABSTRACT:
A closure lining machine comprises a lining applicator 7, a star wheel 4 to receive a closure to be lined and move it to the lining applicator and thence to an outlet 8. The machine also includes a stepping motor 9 driving the star wheel 4, and a control circuit including variable means 17, variable in dependence upon the number of pockets 3 in the star wheel 4. The control circuit controls the stepping motor 9 and hence the movement of the star wheel 4 and also controls the operation of the lining applicator 7 so that upon changing the star wheel 4 to accommodate a different size of closure the control of the rotation of the star wheel 4 and the application of the lining is controlled by the control circuit in response to a change in the signal from the variable means 17.
