Abstract
Abstract The invention relates to a device for introducing and positioning a label the walls of a mold formed in two parts separated by a mold joint, in a machine with a reciprocating cycle for the extrusion/blow molding of hollow bodies, of the type comprising:--a member for storing labels disposed above the open mold,--a vertically mobile jack, disposed above the open mold, associated with means adapted to grip a label in the storage member, then to lower this label into the open mold,--means adapted to maintain the deposited label against the walls of the mold during the path of transfer of this mold, wherein a jack adapted to generate a reciprocating vertical movement is associated with a vertical rigid rod bearing at its end a rigid member adapted to pivot about this end, this pivoting rigid member comprising two rigidly connected arms, one forming a pivot stop when its abuts on the upper part of the mold, the other, vertical, bearing at its other end the label to be deposited.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
243 words
A device for introducing and positioning a label on the walls of a mold formed in two parts separated by a mold joint in a machine with a reciprocating cycle for the extrusion blow-molding of hollow bodies, comprising: (a) a storage member for storing labels, said storage member being disposed above said mold; (b) a reciprocating vertically mobile jack disposed above said mold; (c) a vertical rigid rod, a first end of said vertical rigid rod being connected to said jack, a second end of said vertical rigid rod being surrounded by a hollow mobile extension piece containing a compression spring, said extension piece comprising at its upper end at least one stop, said stop limiting the vertical stroke of said vertical rigid rod by abutting on an upper portion of said mold or on a blowpipe-holder member; (d) a rigid pivoting member being connected to a lower end of said extension piece and comprising an upper arm and a lower arm, said lower arm being fixed to a label-holder; (e) a connecting rod, a first end of said connecting rod being connected to said upper arm of said rigid pivoting member, a second end of said connecting rod being connected to said second end of said vertical rigid rod; and (f) means for maintaining a label against a wall of said mold; wherein said label-holder is adapted to grip a label in said storage member and lower said label into said mold.
Claim 2
Independent Claim
243 words
A device for introducing and positioning a label on the walls of a mold formed in two parts separated by a mold joint in a machine with a reciprocating cycle for the extrusion blow-molding of hollow bodies, comprising: (a) a storage member for storing labels, said storage member being disposed above said mold; (b) a reciprocating vertically mobile jack disposed above said mold; (c) a vertical rigid rod, a first end of said vertical rigid rod being connected to said jack, a second end of said vertical rigid rod being surrounded by a hollow mobile extension piece containing a compression spring, said extension piece comprising at its upper end at least one stop, said stop limiting the vertical stroke of said vertical rigid rod by abutting on an upper portion of said mold or on a blowpipe-holder member; (d) a rigid pivoting member being connected to a lower end of said extension piece and comprising an upper arm and a lower arm, said lower arm being fixed to a label-holder; (e) a connecting rod, a first end of said connecting rod being connected to said upper arm of said rigid pivoting member, a second end of said connecting rod being connected to said second end of said vertical rigid rod; and (f) means for maintaining a label against a wall of said mold; wherein said label-holder is adapted to grip a label in said storage member and lower said label into said mold.
Claim 3
Dependent Claim
17 words
The device of claim 1, wherein said rigid pivoting member is in the form of a boomerang.
Claim 4
Dependent Claim
116 words
The device of claim 2, further comprising a return connecting rod, said return connecting rod being parallel to said lower arm of said rigid pivoting member, a first end of said return connecting rod being connected to said lower end of said extension piece, a second end of said return connecting rod being connected to said label-holder, said return connecting rod, said lower arm of said rigid pivoting member, said lower end of said extension piece and said label-holder forming quadrilateral, wherein said quadrilateral is deformable when said at least one stop of said extension piece abuts said upper portion of said mold or said blowpipe-holder member and said vertical rigid rod compresses said compression spring.
Claim 5
Dependent Claim
14 words
The device of claim 1, wherein the said mold comprises a plurality of impressions.
Claim 6
Dependent Claim
23 words
The device of claim 1 further comprising, a return spring disposed between said lower arm of said rigid pivoting member and said label-holder.
