Abstract: A machine particularly adapted for printing card stock. A head or carriage is mounted to reciprocate over a type bed. The carriage mounts the impression roller, inking rollers, doctor roller and an oscillating roller. The impression roller is mounted on an adjustable eccentric shaft adjustable to compensate for different thicknesses of card stock to thereby control the printing pressure. The impression roller is driven through roller members that move on rails which are coupled by way of a positive clutch to the ends of the impression roller which is positively driven in any adjusted position. The inking rollers, oscillating and doctor roller are mounted between side plates of the carriage, improved means being provided for lifting the inking rollers and for lifting the oscillating roller and doctor roller.

Abstract: In an injection moulding machine comprising two relatively movable platens each carrying a mould part, a stop means is provided which, in a first condition, defines a limit to the relative approach movement of the platens, and in a second condition permits further relative approach movement of the platens, means being provided to change the condition of the stop means from the first to the second condition at a predetermined instant after interruption of the relative approach movement of the platens by the stop means.
