Apparatus for making profiled articles
Abstract
Abstract An apparatus for making profiled articles from an advancing strip of thermoplastic materials such as glass comprising a pair of spaced opposed forming elements which are supported on plates adapted for imparting reciprocatory movement to said forming elements both in a direction towards and away from one another and in a direction of advance of the strip. A rod is pivotably supported on the plates and is movable therewith, and a mandrel is secured to the rod to follow reciprocation of the plates in the direction of advance of the strip and to undergo pivotal movement with the rod. The mandrel is disposed between the forming elements and the advancing strip bent around the mandrel by the forming elements when the latter move towards one another. The rod is pivoted during reciprocatory movement thereof by engagement of a pin on a lever secured to the rod in an inclined guide slot in a fixed member. Such pivotal movement of the rod causes the mandrel first to press the thus bent strip against the forming elements and thereafter to retract therefrom and allow free passage of the thus formed strip.
