Abstract: On the-inside of heated molds hollow bodies are formed by vulcanization, the bodies are formed of elements from natural or synthetic rubber and/or treated elastomers, possibly associated with different materials such as leather, skin, cotton, metals, expanded rubbers and others, combined with each other. A pressurized fluid, such as hot or cold air, vapor or compatible gas, is injected between the hollow bodies being formed. During vulcanization, the components, airtight-coupled with each other along at least a contact and sealing common line, are pushed and kept in forming adhesion against the mold surfaces by the pressurized fluid.

Abstract: A system for the automatic loading and/or unloading of products comprises a store (13, 19) with shelves inclined and provided with a mobile transversal blocking means (9, 12), and at least one traveling lift (3) provided with mobile bearing tops (4), also inclined and provided with at least one mobile transversal blocking means (9, 12). Said inclined shelves and bearing tops (4) are provided with transversal, parallel, idle and inclined rollers (5) whereon a product or a product container (1) can slide by gravity when the blocking means is lowered.

Abstract: A process for manufacturing insoles from flexible, porous and stickable sheet plastic material by sheering the sheet to form a peripheral cut of the insole and an internal cut in the heel area to form an open area surrounded by a land area. The insole is then placed in a mold die and plastic is injected to fill in the open area and surround the land area to conform to a predetermined contour. The insole is stabilized in the die by a plurality of rods positioned within the die.
