Abstract: Sheet material 14, such as a continuous supply of terry cloth towel 16, is moved along its length through a path and toward a cutting station 15 where it is cut into lengths 139. The sheet material is formed with bands 166 extending across its length, such as bands of reduced thickness, and the sheet material is cut in these bands. The bands are detected by rollers 144, 145 at opposite edges of the sheet material as the bands approach the cutting station 15, and each edge portion of the sheet material is fed by feed rollers 51, 52 independently of the other edge portion into the cutting station so as to cause one side of the sheet material which may lag the other side to be properly located at the cutting station prior to cutting the sheet material.

Abstract: A dispenser for serving and severing web from a roll includes a container for supporting the roll and a slotted cutting shelf over which web from the roll is draped. A swing-down cover hinged to the container carries a knife blade aligned with the shelf slot and a retractable sheath which envelops the blade until the dispenser is operated to sever the web. The sheath is an elongated flexible resilient member which is downwardly bowed so that, when the cover is swung toward its closed position, the sheath engages the web on the shelf at the midportion of the web first and then gradually engages web portions outboard from that midportion in a progressive fashion by a rolling clamping action until the entire length of the sheath is flexed flat against the web on the shelf thereby laterally tensioning the web as the blade edge projects through the web into the shelf slot.

Abstract: A method and apparatus for automatically severing individual towels from a length of material comprising a plurality of terry towels. The method includes the steps of measuring slightly less than the supposed length of a towel, then activating a sensor that detects the edge of a cutting space by the change in thickness of the material. The sensor causes feeding of the material to stop with a cut-line at a cutting blade. The first edge of the material is held while a second sensor located the same edge at the opposite side of the material, and the cutting blade is moved with the sensor. The material is stretched to straighten the cut-line, and the cutting blade is caused to cut the material. The apparatus includes feed rolls to move the material, and an encoder measures the length. A roller at one edge of the material detects the change in thickness at one edge, and similar rollers detect the change in thickness at the opposite edge.

Abstract: A film splicer has a base, a lid hinged thereto and carrying a blade, and a film support plate, which plate has two portions carrying pegs for engaging in the sprocket-holes end portions of two lengths of film to be spliced and holding them in desired positions. The said two portions of the plate are separated by a slot and the lid carries a plunger, which as the lid is closed, engages the slot to spread the portions before the cutting knife trims the ends of the lengths of film. After the cutting the two portions move back towards each other, thus compensating for the usual gap which is left between the two film length ends due to the passage of the blade.

Abstract: A moving web of material having a high tendency to elongation under stress, such as woven and non-woven plastic fiber or filament webs, is cut by the combined action of a cutting knife which executes its cutting stroke generally in line with and upstream of the web and a grab knife which holds the web at a station spaced closely downstream from the path of the cutting knife and thereby isolates the small length of web between the two knives while the cutting knife completes its stroke.

Abstract: A wire feeding unit and an associated wire length measuring unit advance supply wire through a cutting zone and at the same time the advanced supply wire is guided by a wire transfer system across transversely spaced endless conveyor chains of a wire propelling conveyor. The feeding unit is automatically stopped when it has advanced a measured length of the supply wire and the transfer system tensions the advanced supply wire while it is held against lengthwise displacement by the stopped feeding unit. The wire transfer system then engages the stopped and tensioned wire length with gripping jaws on the conveyor chains, the gripping jaws are closed, and the supply wire is severed in the cutting zone. Tensioning of the advanced supply wire prevents it from sagging between the transversely spaced conveyor gripping jaws and thereby avoids undesirable length variations of the cut off portion of the supply wire.
