Abstract
An apparatus for forming objects, in particular containers, and for applying respective labels thereto, includes a forming arrangement provided with a punch cooperating with a cavity of a die to make the objects by forming a sheet of thermoformable material. The cavity includes a first wall element and second walls. The first wall element is movable between a first operating position in which it receives a label and a second operating position in which it bounds the cavity in cooperation with the second walls, and supports the label in such a manner that during a subsequent forming operation the label is fixed to, in particular substantially incorporated in, the object.
Claims6
An apparatus for forming and labelling objects, comprising
- (a) a forming device including
- (1) a die including side walls which define an upper cavity and a bottom wall, said die bottom wall further containing a lower chamber communicating with said upper cavity;
- (2) a first punch operable between a first position wherein said first punch is above said upper cavity and a second position wherein said first punch is arranged within said upper cavity;
- (3) a second punch connected with a supporting plate and operable between a first position below said lower chamber and a second position wherein said second punch is arranged within said lower chamber, said second punch including an upper surface which defines a bottom wall of said first cavity opposite said first punch when said first and second punches are in said second positions, respectively;
- (b) a blocking device arranged beneath said die and operable between a first position where said blocking device is spaced from said die bottom wall and a second position where an abutting wall of said blocking device is pressed against said die bottom wall;
- and
- (c) elastic devices connecting said blocking device with said supporting plate, wherein when said first and second punches are in said first positions, respectively, a sheet of thermoformable material is arranged between said first and second punches above said upper cavity, and a band is arranged between said blocking abutting wall and said die bottom wall, an object is formed from said sheet of thermoformable material and a label is separated from the band and bonded to a bottom surface of the object when said first punch is displaced to said second position and said second punch and said blocking device are displaced to said second positions, respectively.
