Abstract

Thermoforming apparatus (1) for thermoforming an article (2), preferably a permeable article (2′), comprising: an elastic membrane (3,3′); a mould (4,4′); a hot air source (5) configured to blow a hot airflow (6) towards a zone (7) of the apparatus (1) configured to receive the article (2,2′) to be thermoformed; an actuation system (8) configured to move the mould (4,4′) towards the membrane (3,3′) or vice versa to compress the heated article (2,2′) between the membrane (3,3′) and the mould (4) such that an elastic force of the membrane (3,3′) on the article (2,2′) forces the article (2,2′) to assume the shape of the mould (4).2. Thermoforming apparatus (1) according to claim 1, wherein the mould (4′) and/or membrane (3′) are perforated so to permit a transit of the hot airflow (6) from the hot air source (5) to said zone (7). Thermoforming process of an article (2,2′) in a thermoforming apparatus (1) comprising an elastic membrane (3,3′), a mould (4,4′) and a hot air source (5), comprising the steps of: heating the article (2,2′) through a hot airflow (6) blew by the hot air source (5); compressing the heated article (2,2′) between the membrane (3,3′) and/or the mould (4,4′) by uniquely moving the mould (4,4′) and the membrane (3,3′) one toward the other such that an elastic force of the membrane (3,3′) forces the article (2,2′) to assume the shape of the mould (4,4′).
