An apparatus (100) for applying pressure to at least a portion of an edge surface (192), which bridges opposing faces (194) of a workpiece (190), comprises a frame (110), a first roller (120), a second roller (130), a rotation-control member (140), a first biasing member (150), and a second biasing member (160). The first roller (120) and the second roller (130) are coupled to the frame (110), are rotatable relative to the frame (110), and are translationally fixed relative to the frame (110). The rotation-control member (140) is movable relative to the frame (110), controlling rotation of the first roller (120) and the second roller (130) relative to the frame (110). The first biasing member (150) is configured to operate in compression along a second axis (102). The second biasing member (160) is positioned, in compression, between the frame (110) and the rotation-control member (140).

A stamping press for stamping a round blank. A ram movable in a stroke direction and in an opposite return stroke direction carries a first stamping tool. A second stamping tool and a stamping ring are supported on a press framework. The stamping tools and a stamping opening formed by the stamping ring are aligned along a working axis. An ejector device serves to eject a stamped round blank from the ring opening. It comprises an ejector pin supported on an actuating device that is movably coupled with the ram. During a return stroke of the ram the ejector pin can apply a force on the second stamping tool in order to press the round blank out of the stamping ring. In a ram movement in the stroke direction the actuating device departs from the second stamping tool and no ejector pin force is applied on the second stamping tool.

A pen assembling press includes a base, a press unit, a carriage, and a positioning arrangement. Actuation of a lever moves an engagement head relative to the base along an actuation axis. A second engagement head is coaxial with the first engagement head. The carriage is movably mounted to the base. The positioning arrangement includes a slot, a plurality of recesses and a pin. The slot extends through the first leg in a direction perpendicular to the actuation axis. The slot has a constant height section having a height. The pin has a shaft and a head. The head is receivable in the recesses. The shaft has a thickness being substantially equal to the height of the constant height section of the slot. The pin is movable relative to the carriage along a pin axis that is perpendicular to the actuation axis to selectively engage and disengage the recesses.

An apparatus and method for forming a tray is provided including a forming plate and the complementary aperture in the mandrel formed to define a space therebetween that deforms the blank into the desired shape of the tray. The space between or tolerance defined by the forming plate and the mandrel is less than the actual thickness of the tray at one or more sections and/or points on the tray, such as at the corners of the tray, in order to crush the foldable material forming the tray at the one or more sections. The crushing of the foldable material at these sections effectively removes any shape memory from the foldable material, such that the tray including the crushed sections retains the shape of the tray without the need for additional securing materials on the tray but without degrading any leak-proof functionality of the tray.
