Abstract: A device for molding a plastic component having at least one undercut is disclosed herein. The device including; a fixed block and a mobile block, the fixed block and the mobile block joining along a joining plane and defining first and second cavities defining a molding cavity to receive the plastic, the molding cavity having a first volume and a main direction of demolding; means of separating the mobile block from the fixed block; at least one mobile insert placed in the fixed block; thrusting means urging the mobile insert toward the mobile block; means for moving the at least one mobile element in a secondary direction not parallel to the main direction of demolding.

Abstract: Tyre (1) for vehicle wheels, includes a body (2) of toroidal shape provided with an inner cavity (3), the inner cavity being provided with an opening (3a) facing a centre (C) of the toroidal shape and with a bead (12) intended for being coupled with a rim of a wheel, the opening (3a) being closed by gluing or welding, the body (2) is made of a material chosen from thermoplastic polyurethane (TPU), thermoplastic elastomers (TPE), polyvinyl chloride (PVC), SEBS, bioplastics, APINAT A.

Abstract: The invention relates to a blind assembly process for at least one component and an assembly device. The blind assembly process for at least one component designed to be placed in a housing that is difficult to access comprises a step for the three-dimensional connection of the component using a link with a multifunction plate a step for formation of the means of positioning the multifunction plate in a first wall in which at least one hole is formed through which the link and the component can pass, the said link positioning the component in space so that once the plate has been positioned, the component is in position in the housing a step in which additional components are fixed onto the component.

Abstract: A process for improving sliding qualities of a slide contact or carriage on at least one rail, and a device for implementing this process. The carriage includes a part intended to be moved along the rail. A section (4) shaped to conform to the rail is placed on the surface of the rail, closely following the contour thereof and smoothing out irregularities or deformations of the rail.

Abstract: A process and a device for packaging products in thermoformed boxes, uses a single strip of thermoplastic or thermoformable material to produce cavities (B) and covers (A) and to fold them down (13) about the product to be packaged before thermowelding (14) their edges.

Abstract: This invention relates to a process for production of shaft passages in a molded plastic part, a mold, and the use of the process of production in, for example, a flap device particularly for a feed system for internal combustion engines, characterized in that it consists of: providing a recess by the advance of a slide of the molding tool between two adjacent bearings each associated with sites of different moving parts, and forming a bearing portion on each side of the sites of each moving part by a moving wedge relative to a slide, whereby the wedge carries a pin that is intended to form a bearing portion of one side of the moving part.

Abstract: A process and an apparatus for handling food, chemical or pharmaceutical products effects sequentially the thermoforming, the loading with products, and the final production of trays for handling the products. These handling trays comprise a receiving recess (8) for the products (P) and a film (3) welded thereover, as well as a cover (9) of one piece with the recess (8) used in the handling of food, chemical or pharmaceutical products.

Abstract: A vehicle door equipment plate incorporating the window winder function and at least one other function is characterized in that it is built into a conventional door structure consisting of a press-formed shell having an outer metal panel connected to an inner metal panel provided with at least two openings separated by a strengthening metal sheet connecting piece placed substantially transversely with respect to a longitudinal direction of the door. One of the openings provides a passage for a window guide element integrated at one end of the equipment plate, the latter being made from moulded plastic.

Abstract: Device for controlling the opening of a blanking off flap of a pipe, wherein the blanking off flap of the pipe is controlled in a first direction by a device using a spring made of a shape memory alloy as soon as the temperature rises and a return spring which activates the flap in a direction opposite the first direction as soon as the temperature drops.

Abstract: Packaging trays are displaced over the entire length of a packaging machine by the horizontal top run of a single conveyor provided with a series of transverse bars which are capable in each case of pushing one of the trays and are attached to driving chains which form a closed loop with the push-bars, the packaging trays being slidably displaced on guide plates or tracks. Moreover, the control elements of the conveyor are capable of subjecting this latter to a forward displacement until a packaging tray is brought onto a platform located within the welding station, then to a slight backward displacement (R) until the corresponding push-bar has withdrawn behind the welding station in order to avoid any interference with the closing of the moving parts of the station, and finally to another forward displacement of the push-bars after completion of the welding operation.

Abstract: A device for producing plastic trays (1) in which two parallel opposed walls (6, 7) are slanted in respect to a plane perpendicular to the sealing plane thereof. The two molding or thermoforming tools (12, 13) in this device are respectively carried by two movable supports (14, 15) capable of moving the tools along an axis (Z--Z') parallel to slanted walls of the tools which correspond to the slanted walls (6, 7) of the tray (1) to be produced. This slanted axis (Z--Z') makes it possible to use simple molding tools, namely an external female tool (12) and an internal punch (14). The packaging plant comprises a tray-forming device (8) as above-described, followed by a welding station (17) for welding a sealing film (18) onto the salient peripheral rim (3) of each plastic tray (1). In this station (17), a movable support member (22) for the tray (1) is movable along an axis (W--W') having the same slant as the sidewalls (6, 7) of the tray.
