Machine for thermoforming and method for thermoforming
11192290 · 2021-12-07 · ·

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.
