Various rosin press assemblies and methods are described. The rosin press assemblies can include a frame, press plates, a user interface, a press system, and a control unit. The frame can include a plurality of support elements, such as plates. Each plate within the frame can have tabs formed on the ends and edges of the plates and can have slots formed in the plates. The tabs from one plate can interlock with tabs or slots from other plates to form an interlocking frame. The interlocking frame can increase rigidity of the frame to prevent the frame from flexing during operation of the rosin press.

A method for monitoring and assessing correct position P.sub.i of a work slide of a wedge drive tool in a press, without a position sensor. The slide of the wedge drive tool is actuated from an end position (X.sub.E) back to the starting position (X.sub.A) of the slide by a spring. The spring is arranged in the wedge drive tool. The press is opened from a lower press position to an upper press position while a slide bed of the wedge drive tool is relieved. The position of the slide is indirectly detected in that at least the restoring force of the spring is detected and evaluated.
