Abstract

Tools and methods for wrapping fibrous sheets with sheets include: Wrapping points with drive rollers The package strip dispenser is equipped with a package sheet guide device.The position of the package strip handler is adjustable. To create an acute angle between the longitudinal axes Of the packing sheet to be discharged by the package sheet carrier and roll circumference direction Fiber material sheet The circumference direction is tangent to the circumferential surface of the roll. And parallel to the spindle end of the roll The packing sheet moves along the axis with the roll. The first strip of the packing material is placed against the roll so that the longitudinal axis of the first strip is placed. Of the package at an acute angle corresponding to the circumference of the fiber roll Bar one of The packaging sheet is wrapped in a spiral around the fibrous sheet.

Claims (15)

1. The method for wrapping a roll of fibrous material with paper packaging material involves the following steps: First, place the first strip of paper packaging material against the roll so that the longitudinal axis of the first strip is at an acute angle to the circumference of the fibrous material roll. This circumference direction is tangent to the circumference surface of the roll and parallel to the end of the axis. Wrap the first strip of paper packaging material in a spiral around the roll of fibrous material so that at least a portion of the circumference surface of the roll at the end remains uncovered. Second, place the second strip of paper packaging material against the roll so that the longitudinal axis of the second strip is parallel to the circumference of the roll. Wrap the second strip around the roll so that the first part of the second strip extends axially beyond the end of the axis of the roll, and a portion of this second strip covers the uncovered circumference surface of the roll. The position of the paper packaging material can be adjusted so that the subsequent wrapping layers overlap. The second strip of packaging material is fed in after the first strip. Packaging material sheets, which are wrapping paper. 2. A method consistent with Reputation 1 in which the position of the packaging material sheet can be adjusted so that the subsequent layers of packaging material overlap. 3. A method consistent with claim 2 where the next wrapping layer overlaps by approximately half the width of the wrapping material sheet. 4. A method consistent with claim 1 where a spiraled sheet of packaging material is placed between the ends of the axis of the roll. 5. A method consistent with Reputation 1 where both the first and second strips of the packaging material sheet are obtained from the same roll of packaging material sheet. 6. A method consistent with claim 1 where the second strip of packaging material is wrapped around the roll with a greater number of layers than the first strip of packaging material. 7. A method consistent with claim 1 in which subsequent layers of packaging material are bonded together with adhesive. 8. A method consistent with claim 1 where the packaging material sheet has a width of at least 350 mm. 9. The equipment used for wrapping fibrous material sheets with packaging material consists of a wrapping point with a driven roller, a packaging strip dispenser with a packaging strip delivery device. The position of this packaging strip delivery device can be adjusted to create an acute angle between the longitudinal axis of the packaging material being fed by the delivery device and the circumference direction of the fibrous material roll. This circumference direction is tangent to the circumference surface of the roll and parallel to the end of the roll axis. The packaging material can move along the axis parallel to the fibrous material roll. A control device connected to a diameter sensing device is used to measure the diameter of the fibrous material roll. This control device regulates and synchronizes the wrapping speed of the fibrous material roll and the forward feed rate of the packaging strip dispenser, which depends on the diameter of the fibrous material roll, where the packaging material is paper. 10. An instrument conforming to claim 9 in which such packing material sheets are dispensed from a roll of packing material with one axis; such roll of packing material is able to move from a position where its axis is parallel to the axis of the packing material roll to a position where the defined axis is at an acute angle between them. 11. An instrument conforming to claim 9 in which the tape dispenser can rotate in alignment with the roll of filament material. 12. Equipment conforming to claim 9 whereby the tape dispenser shall consist of a drive gear to move the tape dispenser along an axis in alignment with the roll of filament material. 13. An instrument conforming to claim 9 in which the dispenser of such packaging material shall include an adhesive applicator. 14. An instrument conforming to claim 13 where such adhesive applicator is of a water-based type. 15. The instrument conforming to claim 14, such gluing device, shall be of the heat-activated type.
