A control method for a mold opening/closing device including a hydraulic cylinder that opens and closes a mold, a hydraulic drive device that drives the hydraulic cylinder by supplying a hydraulic oil, and a controller that controls the hydraulic drive device, wherein the controller changes speed change in a deceleration region, in which movement of the hydraulic cylinder is decelerated, between a first half portion and a second half portion of the deceleration region, and causes speed change rate per unit time in the second half portion to be smaller than in the first half portion.

A device for blow molding containers, provided with a supporting frame for at least one station for blow molding preforms in order to obtain containers, the blow molding station includes two lateral bodies and a bottom which are adapted to provide by blow molding at least one container, at least one of the two lateral bodies being movable on command by virtue of elements for cyclic opening and closing, with respect to the supporting frame, about an articulation axis which is substantially parallel to the axis of the container.

In one embodiment, an apparatus and a method of manufacturing a paperboard tray therewith is provided. In particular, a hub is configured to rotate about a shaft. On the hub, a plurality of first molds are formed in the hub. Conversely, a plurality of second molds are each disposed above each of the plurality of first molds respectively and rotate above the first molds. In this configuration, the plurality of second molds are configured to move in unison with the plurality of first molds as the hub and second molds rotate and to move orthogonally towards and then away from the first molds as the second molds rotate.
