The invention relates to a thermoforming device (10), in particular for cups (1) that can be filled with a foodstuff, having a mold (11) comprising an upper part (12) and a deep-drawing mold (13) arranged underneath the upper part (12) for molding at least one cup (1) in a heated sheet of film (2), wherein the deep-drawing mold (13) forms a side wall (4) and a bottom area (5) of the at least one cup (1).

An apparatus (1) for thermoforming dental aligners provides a support structure (10) on which a rotary table (11) is mounted on which a plurality of operating modules (20) are mounted at an equidistant angle, each comprising a moulding support (21) suitable to house a dental arch (I) and a mounting support (22) suitable to house a disc of thermoformable material (F). The rotation of the table (11) brings the operating modules (20) in succession, at a heating device (30) in which the disc (F) is heated and softened and then at a moulding device (40) in which the mounting support is lowered into a lowered position (PA) to realize a moulding chamber (41) in which by means of an overpressure the disc (F) goes to copy the shape of the dental arch (I) to realize an aligner. An operator can load all the operating modules (20) and start the apparatus (1) in an automatic cycle, which sequentially produces all the aligners without the apparatus needing to be manned by the operator.

A method of creating projections in a substrate is presented. A first device is provided with an outer surface defining recesses, where each recess has a first portion proximate the outer surface with a first perimeter and first depth and a second portion distal the outer surface with a second perimeter and second depth. The first perimeter is larger than the second perimeter and the first depth is less than the second depth. The first portion of the recesses substantially surrounds the second portion of the recesses. The method also includes forming a nip between a source of vibration energy and the outer surface and conveying the substrate through the nip to create precursor projections. The method also includes heating portions of the precursor projections and applying pressure to the heated portions to flatten the portions and increase a perimeter of the portions to form the projections.

A method for forming cellulose products in a mould system from an air-formed cellulose blank structure, where the forming mould system comprises a first mould part and a second mould part. The method comprises the steps: providing the cellulose blank structure, and defining one or more product sections and a residual section; compressing at least a portion of the residual section to a first degree of compression higher than a degree of compression of the one or more product sections; feeding the cellulose blank structure in a feeding direction to a forming position in the forming mould system, where in the forming position each product section is arranged between a corresponding first mould part and second mould part; forming the cellulose products from the cellulose blank structure between the first mould part and the second mould part by heating the cellulose blank structure and pressing the cellulose blank structure.
