To reliably perform partial decoration forming by avoiding crush deformation of a hollow structure due to a change into a pressure-reduced state even in a case where part of the hollow structure is included in a partial decoration forming range of a formed plate material. A surrounding frame body (33) is brought into contact with an upper portion of a body to be coated to surround the decoration forming range, and the body to be coated is accommodated, and an upper space (A) in a sealed state and a lower space in a sealed state are formed. A surrounded space in a sealed state whose top and bottom are surrounded by a decorative film and the body to be coated in the decoration forming range is formed after the lower space and the upper space (A) in the sealed state are brought into a predetermined first pressure state where the pressures in the lower space and the upper space (A) are equal to each other. By instantaneously increasing the pressures in the lower space and the upper space (A) around the surrounded space from the pressure-reduced state to a second pressure state where the pressures are equal to each other while keeping the surrounded space at the first pressure state, partial decoration forming is performed on the decoration forming range in the surrounded space with the decorative film.

A vacuum plastic molding machine includes a heating device, a plurality of upright posts, a carrier assembly, and a demolding mechanism. The carrier assembly includes an upper carrier and a lower carrier. The upper carrier includes an upper frame, multiple upper movement structures, at least one rotation plate, at least one driving member, and at least one linking mechanism. An adjusting space is defined between the at least one rotation plate and the at least one linking mechanism. The lower carrier includes a lower frame, multiple lower movement structures, and at least one locking tenon. The locking tenon is placed into the adjusting space. The at least one driving member is rotated to change the position of the at least one locking tenon in the adjusting space, and to adjust the distance between the upper carrier and the lower carrier.

The present invention relates to a mould system for a thermoforming device and to a thermoforming device with such a mould system (1, 2). The invention further relates to a method for thermoforming a product. According to the invention, the mould system is provided with a punching nipple (6) and a cutting plate (5) whereby a product can be at least partially formed and punched in one operating run.

A deep-drawing apparatus includes an arrangement of die plates, wherein each die plate has a plurality of frame vacuum holes and at least one female die having at least one die vacuum hole. At least one vacuum channel connects a vacuum source to the die vacuum hole of the female die and to the frame vacuum holes of the die plate. The deep-drawing apparatus includes for each die plate a closing device for closing and opening the vacuum channel. The die plate is fed a single foil sheet. The closing device opens the connecting channel at the corresponding die plate and the foil sheet is laid onto the die plate. Thereafter, the foil is held on the frame vacuum holes by a holding vacuum and is deep-drawn by a deep-drawing vacuum at the die vacuum holes in the female die. A method for the deep-drawing of foil is also disclosed.

A thermoform packaging machine including a forming station, a sealing station, a cutting station and a film conveying unit. The film conveying unit includes a clamp chain arranged on a lateral edge of a bottom film, wherein the clamp chain cyclically conveys the bottom film in a direction of production during operation, the bottom film is advanced one cycle length in each cycle of the thermoform packaging machine. Further, the thermoform packaging machine may include a pulling device that pulls a pull section of the bottom film and/or a top film in a direction parallel to the direction of production relative to the lateral edge of the bottom film held by the clamp chain.

A process for making a hermetically sealed package, which includes forming a sheet of wrapping made of plastic material, in particular having a thickness of less than or equal to 140 m. The process envisages: forming on the sheet a first, hollow, portion and a second, perimetral, portion, which delimits at least partially the first portion; inserting the product into the hollow portion obtained in the sheet of wrapping; applying a second sheet of wrapping in contact with the perimetral portion so as to close the hollow portion with the product inside; and welding the second sheet on the first sheet along the perimetral portion. Forming the first sheet includes providing on the second, perimetral, portion a series of pleats of the sheet, which are then sealed.
