A method of manufacturing a wearable article may include providing a modular mold assembly that defines a mold cavity. The modular mold assembly may include a base and a first removable mold tool that interfits with the base. The base may have a mold surface partially defining the mold cavity and the first removable mold tool may have a mold surface disposed at and further defining the mold cavity of the modular mold assembly. A topography of the mold surface of the first removable mold tool may be nonuniform and different than a topography of the mold surface of the base. The method may include disposing polymeric material at the mold cavity, and then thermoforming a bladder in the mold cavity from the polymeric material. The bladder may have an outer surface with a nonuniform topography imparted by the topography of the mold surface of the first removable mold tool.

A forming station for producing a packaging trough by thermoforming at least an area of a film web positioned between a forming tool upper part and a forming tool lower part of the forming station. A male die part of the forming tool upper part may be moved in a vertical direction and inserted into a forming space of a female die part of the forming tool lower part. The packaging trough is produced by deforming the film web between the male die part and an inner wall of the forming space of the female die part. In an inserted condition of the male die part within the female die art, a push-in unit is extended from the male die part towards the inner wall of the forming space at an angular orientation relative to the vertical direction.

A tool for thermoforming a container having a base and an upstanding sidewall walls or walls. The tool includes a mould having a profile shaped to form the exterior shape of the container and a plug adapted to be inserted in the mould to define the interior of the container. The plug has a lower face adapted to define the profile of the base of the container. The profile of the lower face of the plug has at least one groove therein defining, in use, a rib upstanding in the interior of the base of the container.

The disclosure relates to a film transportation plate and a film transportation system for transporting a film web through processing stations of a film packaging machine. The film transportation plate has two opposite lateral edges and, therebetween, at least one mold impression for thermoforming the film web. Retainers for the film web are arranged on the two lateral edges. The retainers are each formed by a fixed clamping surface and at least one clamping jaw, which is movable relative to the clamping surface, for pressing the film web so as to clamp it against the clamping surface. The retainers also each have at least one retaining magnet for attracting the clamping jaw against the clamping surface, and an actuating extension for lifting the clamping jaw off the clamping surface. The film transportation system also includes actuating means which act on the actuating extensions of the clamping jaws.

A thermoforming device includes: an upper hot plate including a first heating surface configured to heat a sheet from above; a lower hot plate including a second heating surface configured to heat the sheet from below; and a substrate-supplying unit including a base configured to hold a molded substrate, and configured to attach the molded substrate to and detach the molded substrate from the base and to dispose the molded substrate at a molding position below the first heating surface with the sheet interposed therebetween, in which the upper hot plate and the lower hot plate are configured to heat the sheet simultaneously from an upper surface and a lower surface of the sheet, the lower hot plate is provided to be movable in a horizontal direction with respect to a position below the upper hot plate, and the thermoforming device die-molds or adheres, onto the molded substrate held by the base, the sheet softened by being heated by the upper hot plate and the lower hot plate.

A container that includes a microwave interactive web at least partially overlying and joined to a three-dimensional support, wherein the three-dimensional support may be formed prior to having the microwave interactive web mounted thereto. The three-dimensional support may be a preformed container that is sufficiently rigid and dimensionally stable for use in containing food.

An assembly for manufacturing containers by thermoforming, which includes a magazine of thermoplastic sheet-like blanks, a feeding station for feeding the blanks, a heating station for heating the blanks, and a station for thermoforming containers starting from the blanks. The feeding station includes a closed-loop path and at least two conveyor elements, which move, following each other, along the path between a loading position, in which the conveyor element faces the blank magazine, and an unloading position, in which the conveyor element faces the heating station. The heating station includes a heating carousel, wherein, in the active condition, the conveyor element in the unloading position moves with a substantially linear motion with a speed that is substantially equal to a peripheral speed of the heating carousel.
