System for joining ends of rubber strips to supply an extruder
A system (10) for butt-joining two or more rubber strips (B1, B2) selected in accordance with a predetermined rubber mixture recipe in order to feed at least one extruder with a complex strip of rubber material (B.sub.12) made from the butt joined rubber strips is disclosed. The system includes at least one conveyor that transports the rubber strips from an inlet (12) of the system to an outlet (14) of the butt-joining system; a frame (18) that operationally supports the conveyor to allow the continuous transport of the rubber strips and also to allow the simultaneous butt-joining of the rubber strips fed to the system; and a roller system (20) that butt-joins the rubber strips without penetration. The invention also relates to a process for butt-joining rubber strips that is performed by the system.
RESIN-SEALING METHOD
There is provided a resin-sealing apparatus that supplies an appropriate amount of sheet-shaped resin for each workpiece, thereby improving the molding quality of a molded product without production of resin dust, such that no redundant resin is produced on a molded product. The resin-sealing apparatus includes a resin supply part that supplies a sheet-shaped resin by cutting out an amount of sheet-shaped resin appropriate for one-time compression molding from a long resin sheet formed to have a predetermined width and a predetermined thickness depending on an amount of resin required for each workpiece, and a transport part that transports the appropriate amount of sheet-shaped resin supplied by the resin supply part to a sealing mold.
