Abstract
Abstract A process and device for applying label and plates on hollow bodies of thermoplastic synthetic substances in which a blow mold has openings therein to guide a punch and is provided with grooves for ventilation purposes. The method includes the insertion of a thin foil into a blow mold and holding the foil in a curved position, corresponding to the curve of the hollow body and finally holding a punch during the blowing process and in a receding position in relation to the walls of the mold.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
188 words
An apparatus for applying labels onto hollow bodies, comprising: a blow mold having a cavity for containing a hollow body; a bore in said mold opening into said cavity; a member movable within said bore from a withdrawn to a mold-closing position at which it forms a section of said cavity, one end of said member having a curvature corresponding to the curvature of said mold cavity and being adapted to receive a label thereon to be applied onto the hollow body in said cavity when said member is in its mold-closing position; and said mold having ventilation openings in communication with said cavity for venting any air out of said mold which may be present between the label and hollow body during movement of said member toward its moldclosing position, said ventilation openings comprising grooves disposed substantially along the entire length of the wall of said bore, each of said grooves being closed at their respective inner ends at said cavity, the apparatus further including a transfer device for picking up the label from a supply station and transferring it to said one end of said member.
Claim 2
Independent Claim
188 words
An apparatus for applying labels onto hollow bodies, comprising: a blow mold having a cavity for containing a hollow body; a bore in said mold opening into said cavity; a member movable within said bore from a withdrawn to a mold-closing position at which it forms a section of said cavity, one end of said member having a curvature corresponding to the curvature of said mold cavity and being adapted to receive a label thereon to be applied onto the hollow body in said cavity when said member is in its mold-closing position; and said mold having ventilation openings in communication with said cavity for venting any air out of said mold which may be present between the label and hollow body during movement of said member toward its moldclosing position, said ventilation openings comprising grooves disposed substantially along the entire length of the wall of said bore, each of said grooves being closed at their respective inner ends at said cavity, the apparatus further including a transfer device for picking up the label from a supply station and transferring it to said one end of said member.
Claim 3
Dependent Claim
55 words
The apparatus according to claim 1 wherein said transfer device is provided with duct means for applying both suction to one end of said transfer device to thereby hold the label in place during pick-up, and for applying positive pressure through said device one end to thereby transfer the label to said member one end.
