Abstract
Abstract A method for the mechanical production of containers and container bottom parts includes the feeding out of a sheet of a material which is thermoplastically deformable and the indexing of the sheet past cutting, heating or molding, filling, covering and sealing apparatus to effect the deep drawing and filling and sealing of the container. The material is fed out and cut into a predetermined length from a web of such material and the individual cut portions are provided with raster holes by means by which the cut elements are centered in respect to the subsequent operations thereon. The apparatus for carrying out the method includes a conveyor having finger elements which are movable to engage in the raster holes of the individual cut elements and to move them to each additional working station and to center them at each station. The web material from which the molded containers are formed advantageously includes a printed distorted picture thereon for facilitating the centering and cutting thereon.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
95 words
A method for the mechanical production of containers, container bottom parts and similar parts by deep-drawing a thermoplastically deformable sheet which is printed particularly with a distorted picture, comprising feeding a continuous strip of the material into a first cutting station and cutting the material to a precise predetermined length and simultaneously imparting a raster hole at two spaced locations on the cutaway portion, and engaging the cutaway portion by engagement in the raster holes to move the cutaway portion to a next operating station and to center it in respect to the operating station.
Claim 2
Independent Claim
95 words
A method for the mechanical production of containers, container bottom parts and similar parts by deep-drawing a thermoplastically deformable sheet which is printed particularly with a distorted picture, comprising feeding a continuous strip of the material into a first cutting station and cutting the material to a precise predetermined length and simultaneously imparting a raster hole at two spaced locations on the cutaway portion, and engaging the cutaway portion by engagement in the raster holes to move the cutaway portion to a next operating station and to center it in respect to the operating station.
Claim 3
Dependent Claim
35 words
A method, according to claim 1, wherein the sheet material is provided with a distorted picture imprint, and wherein the raster holes are located in accordance with the position of the printed distortion picture thereon.
Claim 4
Dependent Claim
59 words
A method, according to claim 1, wherein the cutaway sheet is centered at a heating station and heated, is thereafter moved in respect to a molding station where the containers are deep-drawn molded, is thereafter moved to a filling station where the container is filled, and is thereafter moved to a covering station where a cover is applied thereto.
Claim 5
Dependent Claim
52 words
A method, according to claim 3, wherein said cut portion is wide enough to provide two separate container formations at the molding station, and subsequent to applying a cover over the both of said container portions moving the covered container portions to a punching station for separating the containers from each other.
Claim 6
Independent Claim
116 words
An apparatus for indexing a cut sheet of material through a molding process for the formation of containers and the like, comprising photocell control means, feed means for moving a continuous sheet of material into association with said photocell control means, cutting means connected to said control means for cutting a precise cut length away from the sheet of material and for simultaneously defining a raster hole at two spaced locations on the cutaway portion, a plurality of work stations for operating on the cutaway sheet material including a heating and molding station and conveyor means for engaging the cutaway portion and for indexing it through and centering it in said a plurality of work stations.
Claim 7
Independent Claim
116 words
An apparatus for indexing a cut sheet of material through a molding process for the formation of containers and the like, comprising photocell control means, feed means for moving a continuous sheet of material into association with said photocell control means, cutting means connected to said control means for cutting a precise cut length away from the sheet of material and for simultaneously defining a raster hole at two spaced locations on the cutaway portion, a plurality of work stations for operating on the cutaway sheet material including a heating and molding station and conveyor means for engaging the cutaway portion and for indexing it through and centering it in said a plurality of work stations.
Claim 8
Dependent Claim
46 words
A device, according to claim 5, wherein said conveyor means includes a rotatable and axially displaceable shaft member, and a finger carried on said shaft member being rotatable therewith to position the finger to engage in a raster hole which is defined by the cutaway portion.
Claim 9
Dependent Claim
55 words
A device, according to claim 6, including a tubular receiver member carried by said conveyor and being positionable below the raster hole of each cutaway portion, said finger being movable through the hole to engage in said tubular receiver member to hold the sheet by said conveyor means for movement through the various work stations.
