Machine for thermoforming and method for thermoforming
A thermoforming machine and a thermoforming method are provided, in particular for producing capsules for obtaining beverages. The capsules (C) are produced from a film (F) of thermoformable material by thermoforming one or more predefined portions (X) of the film. The one or more predefined portions (X) of the film of thermoformable material are pre-heated, i.e. they are heated before being subjected to thermoforming so as to minimize the probability that the film of thermoformable material tears or breaks during thermoforming or after thermoforming.
APPARATUS AND PROCESS FOR MAKING SUPPORTS OR PACKAGES, AND PACKAGING APPARATUS AND PROCESS
An apparatus (100) for manufacturing supports (6) and/or packages (80) comprising a supplying station (1) presenting a roll support (1a) configured to receive a feed roll (2) and to rotate it around a respective unwinding axis (A) to unroll consecutive portions of plastic film (3); and a cutting station (10) configured for carrying out a cutting procedure comprising separating, from an unrolled portion of plastic film (3) coming from the feed roll (2), either a strip (4) or a plurality of distinct film sheets (5) obtained from a same strip shaped portion (400). The strip (4) or the strip shaped portion (400) have a width, measured parallel to the unwinding axis (A), and a length, measured perpendicular to the unwinding axis (A), wherein the width of said strip shaped portion (400) is larger than the length of the same strip shaped portion (400). The apparatus (100) also comprises a thermoforming station (20) receiving and thermoforming the strips (4) or the distinct film sheets (5), and/or a packaging station (30) configured for closing in a package
Composite sidewall and cargo body having same
A composite molded cargo body panel including a core, an interior skin secured to a first side of the core having a thickness, and exterior skin secured to a second side of the core, and a plurality of recesses. The plurality of recesses are dispersed along a first direction at intervals in the interior skin, with the core thickness at each of the plurality of recesses being reduced compared to a maximum core thickness, and each of the plurality of recesses defines a support surface. A pocket is formed in each of the plurality of recesses, with the core thickness at the pocket being less than the core thickness at each of the plurality of recesses. A plurality of logistics inserts are attached to the respective support surfaces of the plurality of recesses so that, at each of the plurality of recesses, the logistics insert extends across the pocket.
Systems and methods for thermoforming thermoplastic structures
A system for forming a thermoplastic may comprise a mandrel configured to receive a thermoplastic charge. The mandrel may rotate about a mandrel axis. A series of rollers may be located circumferentially about the mandrel and configured to apply radially inward pressure. A heating element may be located upstream of the series of rollers.
THERMOFORMED TUBE HEAD, TUBE AND MANUFACTURING METHOD
The invention relates to a tube head (1, 2) intended to form a packaging, the head (3, 6) being intended to be welded to a tubular skirt (8, 9) in order to form the said packaging, and the tube head (1 2) being thermoformed from a sheet (20, 21). The invention also relates to a method for manufacturing such a tube head (1, 2) and a tube with said head (3, 6).
THERMOFORMING DEVICE AND THERMOFORMING METHOD
A thermoforming device includes: a base configured to hold a substrate; a hot plate including a heating surface facing vertically downward; a sheet transport portion that supplies a sheet onto the heating surface of the hot plate; and a substrate supply portion configured to attach the substrate to the base and detach the substrate from the base, and to dispose the substrate at a substrate supply position positioned in a lower area of the sheet which is opposite to a side of the sheet in which the heating surface is provided. In the thermoforming device, heating of the sheet using the hot plate and attachment and detachment of the substrate with respect to the base are performable at the same time, and the sheet heated and softened by the hot plate is attached to the substrate at the substrate supply position.
CONTINUOUS MOLDING METHOD AND CONTINUOUS MOLDING APPARATUS OF PRESS MOLDED PRODUCT
A strip-shape softened resin sheet (S) which is continuously extruded from a molten resin extruder is cut to a unit resin sheet and a press molded product is manufactured by press-molding the unit resin sheet in a press-molding machine. Prior to cutting the continuously extruded strip-shape softened resin sheet (S) to the unit resin sheet (U) , the slits C.sub.1, C.sub.2, C.sub.3, C.sub.4 and C.sub.5 which promote the molding to the press molded part from the unit resin sheet (U) (improve an inflow property of the material) are formed by a cutter which is upwardly and downwardly driven by an air cylinder at a portion P.sub.3 in which the material therein is out of a range of the press molded products P.sub.1 and P.sub.2 obtained by press-molding the press molded product by using the press molding machine and becomes a scrap. The inflow property of the resin material for vertical walls and embossment portions when press-molding is improved and the defects of the product can be prevented.
CONTINUOUS PRESS-MOLDING METHOD AND HEATING MACHINE THEREFOR
A strip-shape softened resin sheet (S) which is continuously extruded from a molten resin extruder is cut to a unit resin sheet and a press molded product is manufactured by press-molding the unit resin sheet in a press-molding machine 20. Prior to press-molding the unit resin sheet (U) by the press-molding machine, the unit resin sheet (U) is heated by a heating machine 16. The heating machine 16 comprises a first heating furnace 84 and a second heating furnace 86. The first heating furnace 84 includes a series of heaters 84-3 and 84-4 whose heat source is infrared ray in a far-infrared region and the second heating furnace 86 includes a series of heaters 86-3 and 86-4 whose heat source is the infrared ray in a middle-infrared region. In the first furnace 84, the unit resin sheet (U) is continuously conveyed with a low velocity and is gradually heated by the far-infrared ray up to temperature which is slightly lower than the temperature which is suitable for press-molding the unit resin sheet (U). In the second furnace 86, the unit resin sheet (U) is stopped and is rapidly heated by the middle-infrared ray. By efficiently heating the unit resin sheet (U), a cycle time can be shortened and the production speed can be improved.
Thermoformable semi-rigid orthoses
An orthosis for supporting a limb or a joint of a human or of a vertebrate animal, including: a sleeve which is at least partly elastic and is designed to enclose a limb or a joint, a plate made of a thermoformable material, and a pocket formed on the sleeve in order to receive the plate, the pocket having a shape adapted to that of the plate. The adherence between the plate and the inner surface of the pocket is treated in order to permit a relative movement of the plate with respect to the material forming the pocket during and after an operation of thermoforming of the plate, this being done by placing the orthosis on the limb or the joint with the plate present in the pocket. This orthosis is designed to be fitted in place and thermoformed by the user himself.
COMPOSITE SIDEWALL AND CARGO BODY HAVING SAME

The plurality of recesses are dispersed along a first direction at intervals in the interior skin, with the core thickness at each of the plurality of recesses being reduced compared to a maximum core thickness, and each of the plurality of recesses defines a support surface. A pocket is formed in each of the plurality of recesses, with the core thickness at the pocket being less than the core thickness at each of the plurality of recesses. A plurality of logistics inserts are attached to the respective support surfaces of the plurality of recesses so that, at each of the plurality of recesses, the logistics insert extends across the pocket.
