Abstract:
A coreless surface winder and method wherein one of the winding rollers is accompanied by a slightly spaced apart arcuate dead plate which operates to cause a folded leading edge on a transversely severed web to roll upon itself and develop an incipient log which thereafter is completed in a conventional three roll cradle to provide a coreless retail sized roll.
Abstract:
A media transport apparatus including a supply of recording medium, collecting means for the recording medium, a drive roller for moving the recording medium from the supply to the collecting means along a transport path, and a cutter for severing the recording medium into sections. The cutter is located between the drive roller and the collecting means and is moved in a direction substantially transverse to the direction of movement of the recording medium during severing. Deflectable fingers define a portion of the transport path in interference relationship with the cutter and are readily displaced by the cutter while continuing to provide a rigid guide for the recording medium.
Abstract:
A copying/printing machine is adapted for rolling up copies of large size documents such as engineering drawings and the like by incorporating a roll-up apparatus into the machine. An output copy is guided along a circular interior space formed by a combination of curved baffle members. The copy is propelled along a spiraling inward path by a combination of feed rollers and nudging rollers spaced along the width of the baffle members. A portion of the roll-up apparatus is pivotable downward to permit the rolled-up output document to be removed.
Abstract:
A method and apparatus is provided for tightly rolling mats. The mats are moved in a horizontal direction in their flattened condition to a rolling section which includes a plurality of fixed curved fingers and a corresponding plurality of curved spring-loaded fingers. A roller is further provided to move the mat upwardly from the conveyor forming a tight cylindrically shaped mat inside the curve of the fingers. Upper belts are provided above the fingers to further ensure that the mat is rolled tightly.
Abstract:
In order that a roll which is at least as highly compacted as that according to EP No. 0 031 286 Al may be obtainable trouble-free and with less expenditure of material and labor in the production of reelless rolls by laying the netting in zigzag formation and rolling it up by means of inclined guide surfaces followed by winding portions which constitute a receiver of variable shape for the roll and are displaceable in their longitudinal direction, it is proposed that the winding operation should be carried out intermittently; the partially completed roll should be rolled over the adjoining netting which is laid in zigzag formation, and the roll, having been thereby enlarged, should be transported back to what was its starting point before this rolling movement, and these procedures should be repeated cyclically. For this purpose, a winding driving device is provided to shorten the winding portions for the purpose of rolling up the netting, several transport portions (88) also adjoining the guide surfaces (40) are provided for returning the roll to its starting position, and a transport driving device is provided for transporting the roll with simultaneous lengthening of the winding portions.
Abstract:
Rollable sheet handling apparatus receives advancement of a sheet in a longitudinally forward direction. The apparatus comprises:(a) means to receive the advancing sheet and to roll same,(b) the means including support means over which the sheet travels, and auxiliary means including swingable arm means and rollers carried by the arm means to be movable between rearwardly collapsed position in which rolling of the sheet extent adjacent the support is initiated, and a series of forwardly extended positions in which rolling of the sheet is guided toward completion, and while the rollers engage the sheet extent being rolled,(c) the rollers being spaced to extend about, in roll forming relation, a portion of the sheet extent initially being rolled.
Abstract:
Apparatus is provided for packaging strips of flexible, compressible material, such as layers of glass fibers. The compressible strip is wound under compression into a roll by the apparatus to provide a compact package. The compressed package can then be held in that state by tapes or the like which are automatically fed into contact with a trailing end portion of the compressible strip as it is being rolled up. The packaging apparatus includes a generally horizontal conveyor which carries the strip along a generally horizontal path. An upright, back-up belt conveyor is positioned to intercept the strip in its path and to deflect the forward edge of the strip upwardly away from the path. An infeed or guide roll helps to guide the forward edge of the strip toward the upright conveyor and a compression or tuck roll helps to turn the forward edge back downwardly after it is directed upwardly by the belt conveyor and to cause the strip to begin to roll into a spiral package. One side of the package then is contacted by an upwardly moving run of the conveyor belt and the other side of the package is contacted by the tuck roll which is driven in a manner to move the package in a direction opposite to the back-up conveyor. The tuck roll is also urged toward the backup conveyor so as to maintain compression on the strip as it is being rolled into the package. As the package is being completed, tape is dispensed on the horizontal conveyor and carried into contact with the trailing end of the strip and the outer wrap of the package so as to hold the strip in its packaged condition. At this time, the back-up conveyor is swung away from the horizontal conveyor and away from the path of the strip with the strip package then being ejected beyond the back-up conveyor where it can be transferred to a shipping point or processing station, by way of example. The packaging apparatus is also equipped with adjustments which enable it to accommodate strips of fibrous material of widely varying thicknesses.
Abstract:
A paper stick-forming device which converts a paper sheet into a hollow stick suitable for lollipop handles, pencils, and other short stick applications. The paper sheet is first introduced into a cutoff device where portions having the proper length are cut from the sheet. Then the portions are curled by supporting them on a polyurethane covered roll and by passing them under a curling wire comprising a hard, thin cylinder of tungsten carbide. The roller which supports the curling wires also includes open circular recesses between each wire for storing the rolled paper portions until they are delivered to a belt conveyor.
Abstract:
Apparatus for use in winding peat band rolls is provided wherein a pair of winding rolls is adapted to engage opposite sides of the forming peat band roll which is carried on a conveyor belt. The winding rolls are connected to rotatable lever arms which are in turn connected to eccenters, the eccenters being adapted to lift said winding rolls away from the completed peat band roll to permit its removal by the conveyor belt.
