A system for the continuous extrusion, molding, and curing of tread for tires. An elongated strip of rubber material can be molded and cured shortly after extrusion such that the material retains much of the heat energy of extrusion and does not have to be stored. A plurality of discrete mold assemblies are conveyed adjacent to each other. As the mold assemblies are advanced sequentially, the uncured and unmolded strip of rubber material are extruded and positioned onto the mold assemblies. While the rubber strip advances, individual portions are sequentially molded and cured by passing through a mold press and then a curing press. A plug assembly is used to prevent the backflow of rubber material during the molding and curing.

A vacuum probe comprises a sharpened body that is displaceable downward and toward a vacuum bag during vacuum hose quick connection. The sharpened body and a valve element inside the vacuum probe move in tandem until the sharpened body projects outside the vacuum probe. A vacuum pressure applied via the vacuum hose pulls the vacuum bag upwards and towards the projecting sharpened body, which then punctures the vacuum bag, thereby enabling air under the vacuum bag to be evacuated via the vacuum probe as vacuum pressure continues to be applied.

A compression mold includes a first mold and a second mold. The first mold includes a side surface member and a bottom surface member. The side surface member includes a step height on a bottom surface member side of the side surface member. The step height includes a first surface of the side surface member, a second surface that extends from the first surface toward the bottom surface member, and a third surface that extends downward from the second surface. The bottom surface member includes an upper surface where a resin material can be arranged and a slide surface that extends downward from the upper surface and is slidable with respect to the third surface of the side surface member. The third surface of the side surface member is not exposed while the resin material is supplied.

A system for handling culinary preparations, which includes: a mounting (I) including an upper surface arranged to receive a culinary preparation, and a plurality of feedthroughs extending between the upper surface and a lower surface; a transfer device including a plurality of projecting portions; a relative movement system being arranged to position the system in a low position, in which no projecting portion projects relative to the upper surface of the mounting, and a high position, in which one end of at least one projecting portion is made to project through the feedthroughs, relative to the upper surface of the mounting; and a handling tool including oblong elements arranged to be inserted between projecting portions.

A device for forming a sheeted dough from a dough piece, which includes: (i) a lower tray arranged so as to support the dough piece during a forming operation, (ii) an upper tray, and (iii) a forming actuator arranged so as to move the upper plate in relation to the lower plate, in such a way as to be able to press the dough piece between the lower tray and the upper tray in order to form a sheeted dough, the lower tray containing a system of mobile ejectors that can assume a so-called retracted position in such a way as to form, overall, a continuous surface with the lower tray, and a so-called raised position in such a way as to form a raised surface in relation to the lower tray.

The equipment for the production of slabs in mineral grits bound with resins, comprises: a support frame, at least one lower plate, locked together with the frame, comprising at least one positioning zone for at least one mold having at least one forming cavity, open at the top, to contain a mix comprising the materials necessary to obtain the slabs, at least one pressing assembly comprising an upper plate movable, with respect to the frame, from an upper position of loading/unloading the mold in/from the positioning zone, to a lower position of pressing the mix inside said forming cavity, vibrating means associated at least with the lower plate, and an airtight chamber, communicating with suction means, adapted to reduce the pressure to a value lower than the atmospheric pressure, containing the mold, where the chamber is interposed between the lower plate and an upper closing element opposite the lower plate.

According to one implementation, a composite material forming jig includes molds and a tilting structure. The molds are developable for laminating fiber sheets, after or before impregnated with a resin, in a developed state where the molds are developed. At least one mold of the molds is capable of being inclined relatively to another mold of the molds so that the laminated fiber sheets are shaped. The tilting structure is adapted to develop the molds when the fiber sheets are laminated and incline the at least one mold when the laminated fiber sheets are shaped.

A molding process according to one embodiment of the present disclosure includes injecting a first molding material into a mold cavity of a mold, the mold cavity formed by at least a mold cavity portion of a first platen and a second platen when the first platen is in contact with the second platen; opening the mold by separating the first and second platens; placing a second molding material at the first molding material while the first molding material remains with the first platen or the second platen; sealing a space between the first and second platens; removing a gas from the space while the space is sealed; and closing the mold while the space is sealed.

A mold assembly for producing a part includes a first section, a second section movably coupled to the first section, and a cavity defined by the first section and the second section, the cavity being shaped to receive a part while the first section and the second section are movably coupled to each other. The mold assembly includes a joint formed by adjacent surfaces of the first section and the second section and a seal extending along the joint.
