Abstract:
A method and an apparatus for the splicing of sheet material, especially for forms made up as packages containing the forms as a continuous accordion folded strip, particularly for the continuous feeding of fast printing machines wherein the bottom form group of each package is placed sideways in respect to the lying plane of the forms within the package, whereby the last form of the in-feeding package is spliced to the first form of another package, the apparatus comprising a splicing plane consisting of two semiplanes whereupon the two sheets or forms to be spliced are placed and retained, upon having spread along the splicing line a length of adhesive tape and having the same sized and trimmed, apparatus being furthermore provided for pressing the edges of the two sheets to be spliced against the adhesive face of the tape, and apparatus for the final trimming of the spliced junction.
Abstract:
Herein disclosed is a splicing apparatus for splicing together the leading end face of one of cord ply segments and the trailing end face of another cord ply segment positioned in front of one of the cord ply segments. The apparatus comprises a first conveyor having a first surface, a second conveyor fixed with respect to the first conveyor and having a second surface spaced apart from and in face-to-face relationship to the first surface of the first conveyor and for conveying the cord ply segments on the second surface thereof in a second conveyance direction substantially in parallel with the first conveyance direction of the first conveyor, and transfer members for transferring each of the cord ply segments on the first surface of the first conveyor to the second surface of the second conveyor. The cord ply segments are transferred from the first conveyor to the second conveyor to splice together the leading end face of one of cord ply segments and the trailing end face of another cord ply segment positioned in front of one of the cord ply segments already transferred on the second conveyor.
Abstract:
A tape splicing apparatus in which two tapes are quickly joined with no air bubbles entrapped by splicing tape. A drum body holds splicing tape by suction pressure applied through holes and the peripheral surface of the drum. The splicing tape is cut into segments of predetermined length upon the drum surface. The drum is then lowered to the splicing position upon stationary and movable receiving stands to press the sticky side of the tape segment against the abutting tape joint. A movable roller presses the splicing tape segment, which was initially attached along only a single line, in forward then rearward directions from the center of the joint so that no air can be entrapped under the splicing tape.
Abstract:
Self-adhesive labels mounted on a backing strip are formed into fan-folded sets or stacks and are loaded directly from the fan-folding machine into an open four-sided cassette. The cassettes are made of cardboard, and after they are loaded with fan-folded labels, they are enclosed either by the addition of a fifth side or by wrapping. The cassette packages are then transported to the location where labels are to be applied to products moving along a conveyor. The fan-folded labels are supported in an open L-shaped rack which is tilted and which is of sufficient length to hold at least two sets or cassettes of fan-folded labels side by side. The labels are fed directly into a standard type of label dispenser which applies the labels to products as they are moving along a conveyor line. As labels are used up, the free end of the first stack of fan-folded labels may be spliced to the second stack of labels so that the high speed labeling machine does not have to be stopped for re-loading a fresh reel of labels, but the labeling process may continue without downtime.
Abstract:
A machine for splicing or joining the ends of two precured rubber tread strips each having a pattern of ribs and grooves in one surface thereof. The machine includes first and second tread-clamping assemblies each of which grips the opposite surfaces of one of the tread strips between two elements and further includes power means for moving one of the assemblies toward the other in order to tightly abut the ends of the tread strips while heat is applied to effect vulcanization of a bonding material which previously has been inserted between the ends.
Abstract:
An apparatus for attachment to a recording machine of the type in which a printed record is made on a continuous strip of paper, such as a paper tape, traveling over a rotating platen wherein the tape is fed into the machine from a tape roll. The apparatus comprises a support frame having a pair of laterally spaced frame members which are interconnected in such a manner that the distance between the members may be selectively adjusted to accommodate tapes of varying widths. The frame members have spaced spindles which mount a feed roll that supplies the paper tape to the recorder machine, while a second pair of spaced spindles are carried by the frame members for rotatably mounting a take-up reel. The end of the tape passing through the recording machine is attached to the take-up reel in such a manner that the tape may be rewound thereon. Means carried by the frame members bias the take-up reel and the feed roll toward one another such that as tape is withdrawn from the feed roll, the frictional engagement with the take-up reel rotates the same in such a manner that the tape leaving the recording machine may be rewound for reuse. In one embodiment of the invention means are provided for selectively cutting and/or splicing the paper tape after it leaves the recording machine.
Abstract:
A crop shearing and joining method and apparatus includes a manually operable crop shearing assembly for producing clean linear edges at the ends of respective strips, sheets or the like, and a joining assembly for welding or otherwise securing the ends of two different strips or sheets together. Also, a strip aligning and clamping assembly comprising two independently operable clamping devices utilizes one of the clamping devices to provide an alignment stop for aligning the end of one strip relative to the welding torch or the like in the joining assembly and then uses that aligned strip end to facilitate alignment of the strip end to be joined therewith. Moreover, the clamping devices provide substantially full backing support of the aligned strip ends during the joining operation.
Abstract:
Disclosed is a sheet splicer for splicing sheets of paper, sheet or film, especially for splicing paper rolls together to form a continuous web joining the old and new rolls of paper when used in continuous web printing presses so that they can be spliced together by a butt end splice. A traverse blade cuts both the old and new plies along a butt edge line. The blade is followed by a tape applicator and paper stripper which strips the selvage and then joins the plies together as a butt edge seam of the old and new sheets. The splicer is designed as a stand alone unit or as an in-place attachment for a printing press.

Abstract:
An apparatus for fabricating and adhesively uniting parallel webs or strips of material by an edge-to-edge adhesive joint, consisting of a cutting device for providing clean cut web edges, and a joining device. The joining device consists of a lower part beneath the web and an upper part above the web, each part comprising a roll of adhesive tape and a pressure roller, both rollers being in contact along a surface line in the plane of the web, the upper part and lower part being rigidly connected to one another by a narrow bar which extends obliquely of the plane of the web and which passes through the cut in the web which is produced by the cutting device.
