Abstract

Abstract Apparatus for forming containers from webs of plastic material is disclosed as including a forming machine and a web tensioning and feeding apparatus. The web tensioning and feeding apparatus feeds the plastic material to the forming machine in accordance with the consumption of plastic material by the forming machine and maintains a relatively constant tension in the plastic fed to the forming machine. The forming machine forms containers from the plastic material and includes printing apparatus for printing on the formed containers. The printing apparatus includes a platen with a roller adapted to be rolled on the platen to ink the platen so it can subsequently print on the container. Means are provided for disengaging the forming, blanking and printing devices from the main power drive and bringing these devices to a complete and instantaneous halt even while the motor is running.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 348 words
Container forming apparatus for forming containers from a web of material and printing on the formed containers comprising: a. means for supporting a roll of the material so the roll is free to rotate about its axis and be unrolled, b. selectively actuatable movable means adapted to be in frictional contact with the roll of material to unroll the material upon being moved, c. a forming machine including container forming means, d. means to transfer the material from the roll to the fOrming machine and for applying a relatively constant tension to the material as it is being so transferred and for controlling the movement of said movable means and thus the unrolling of the material from the roll in accordance with the consumption of the material by the machine, e. a printing platen having a printing surface located within the machine, f. an inking roller within the machine and movable between a first and second position, g. means for moving said inking roller from the first position to the second position and in so doing rotating said inking roller so that said inking roller will roll along said platen printing surface to ink said surface and after inking said platen printing surface move said inking roller back to the first position, h. means for preventing contact between said platen printing surface and said inking roller as said inking roller is moved from said second position to the first position and for bringing said platen printing surface into contact with the container to print thereon after the inking roller is returned to the first position, i. said inking roller being defined by a cylindrical member having helical grooves on its periphery, and j. means for instantaneously halting movement of said container forming means, said printing platen, the movement of said inking roller between first and second positions, said inking roller moving means and said means for preventing contact between said inking roller and said platen as said inking roller is moved from the second position to the first position and the movement of said platen toward the container.
Claim 2
Dependent Claim 348 words
Container forming apparatus for forming containers from a web of material and printing on the formed containers comprising: a. means for supporting a roll of the material so the roll is free to rotate about its axis and be unrolled, b. selectively actuatable movable means adapted to be in frictional contact with the roll of material to unroll the material upon being moved, c. a forming machine including container forming means, d. means to transfer the material from the roll to the fOrming machine and for applying a relatively constant tension to the material as it is being so transferred and for controlling the movement of said movable means and thus the unrolling of the material from the roll in accordance with the consumption of the material by the machine, e. a printing platen having a printing surface located within the machine, f. an inking roller within the machine and movable between a first and second position, g. means for moving said inking roller from the first position to the second position and in so doing rotating said inking roller so that said inking roller will roll along said platen printing surface to ink said surface and after inking said platen printing surface move said inking roller back to the first position, h. means for preventing contact between said platen printing surface and said inking roller as said inking roller is moved from said second position to the first position and for bringing said platen printing surface into contact with the container to print thereon after the inking roller is returned to the first position, i. said inking roller being defined by a cylindrical member having helical grooves on its periphery, and j. means for instantaneously halting movement of said container forming means, said printing platen, the movement of said inking roller between first and second positions, said inking roller moving means and said means for preventing contact between said inking roller and said platen as said inking roller is moved from the second position to the first position and the movement of said platen toward the container.
Claim 3
Dependent Claim 15 words
An apparatus according to claim 1 wherein said instantaneously halting means comprises a braking means.
Claim 4
Dependent Claim 38 words
An apparatus according to claim 2 wherein said braking means includes a caliper disc rotatable with said movements, and a caliper brake for said caliper disc for halting rotation of said caliper disc and thereby halting said movements.
Claim 5
Dependent Claim 83 words
A container forming apparatus according to claim 2 and further comprising: a rotatable power shaft, said braking means being connected to said power shaft, main drive means for driving at least a portion of said apparatus and said power shaft, and a clutch for selectively disconnecting said rotatable power shaft with respect to said main drive means, whereby the drive to said rotatable power shaft can be disengaged by said clutch and said rotatable power shaft can be stopped by said braking means.
Claim 6
Dependent Claim 13 words
The apparatus according to claim 4 wherein said clutch is a jaw clutch.
