Abstract:
1. Method of manufacture of receptacles by thermoforming comprising: placing of decorative banderols on the receptacles; providing a first mold block which comprises at least one thermoforming chamber and which is capable of tilting between a working position for vertically thermoforming of receptacles and a tilted position for the introduction of a decorative banderol into the thermoforming chamber before the thermoforming of a receptacle in the said chamber; providing at least one second mold block analogous to the first mould block and wherein while the first mould block is in the working position for the thermoforming of a receptacle in the thermoforming chamber of the first mould block, the second mould block or, one of the second mould blocks, is in the tilted position for the introduction of a decorative banderol into the thermoforming chamber of the second mold block before the thermoforming of another receptacle in the chamber of the second mold block; wherein the method further comprises moving one of the mould blocks in the working position between a thermoforming position in which a receptacle is thermoformed in a thermoforming chamber of this mould block and a removal position in which the receptacle which has just been thermoformed is removed, and wherein the moving simultaneously translates another mould block or blocks between a tilted position at a first level and a tilted position at a second level, and further comprising introducing banderols in said another mould block or blocks in the tilted position at a first level and in the tilted position at a second level.
