Process and Device for Producing a Flowable Product Package Via a Shell In a method for manufacturing a half-shell from thermoplastic material, a plate-shaped section, to be worked, of the plastics material (40) is transported downwards on a vertical web (21) through at least two heating stages (45), arranged one behind the other in the direction of movement (21, 24) to a deep-drawing station (16, 24) and subsequently deep-drawn. In order that the heating of the plastics material prior to deep-drawing can be done more easily and reliably from a technical point of view, it is proposed according to the invention that the plastics material is supplied in the form ofa continuous web (40) from above the first heating stage (45), with heating of the web sections during the movement, vertically downwards to the deep- drawing station (24), on the top end (46) of which the frontmost, lowest plate- shaped section is separated (by 47) during deep-drawing and is deep-drawn.
Dans un procédé de fabrication d'une coque en matière plastique thermoformable, une section de matière plastique à façonner en forme de plaque (40) est transportée, sur une voie verticale (21) à travers au moins deux étages d'échauffement (45) disposés l'un derrière l'autre dans le sens du mouvement (21, 24), vers le bas jusqu'à une station d'emboutissage (16, 24), puis emboutie. Afin que l'échauffement de la matière plastique avant son emboutissage puisse être techniquement plus facile et plus fiable, l'invention prévoit que la matière plastique soit amenée sous forme de bande continue (40) depuis le haut du premier étage d'échauffement (45), les sections de bande se chauffant pendant leur déplacement vertical de haut en bas jusqu'à la station d'emboutissage (24), à l'extrémité supérieure (46) de laquelle la section inférieure en forme de plaque située à l'avant est séparée (par 47) de la bande de plastique (40) lors de l'emboutissage, puis emboutie.
