Abstract (en)
[origin: DE4112179C1] In the process proposed, moulded articles (10, 12) are heated to a temperature corresponding to the softening point of those articles (10) with the lowest softening point. These articles (10) are heated until they have lost their original shape and become reduced in volume. The deformed articles (10') are then separated from those whose shape has remained unchanged.
Abstract (fr)
Les pièces moulées (10, 12) sont portées à une température correspondant à la température d'amollissement des pièces moulées (10) ayant la température d'amollissement la plus basse. Ces pièces moulées (10) sont chauffées jusqu'à ce qu'elles aient perdu leur forme originale par réduction du volume. Ensuite, les pièces moulées déformées (10') sont séparées des pièces moulées restant inchangées.
