摘要:
Apparatus for applying disc-shaped end walls to the end faces of rolls of convoluted paper in a positioning unit wherein the rolls are maintained in horizontal positions has a magazine with two rows of floor-mounted pallets for stacks of superimposed end walls having different diameters. A conveyor which is mounted for travel between the two rows of pallets has lifters which can simultaneously pick up end walls from selected pairs of transversely aligned stacks and delivers the thus lifted end walls to an orientation changing unit which moves the end walls from horizontal into vertical planes and centers the end walls prior to applying them to the respective end faces of the roll in the positioning unit.
摘要:
A method for packaging a web roll, where a packaging sheet is wrapped in a helical line around the web roll, in order to create a body packaging, and where the packaging sheet is wrapped in the circumferential direction around the web roll at the beginning and/or end of the web roll, to form a substantially uniformly shaped axial projection during creation of end packaging.
摘要:
A device and method for packaging a web roll, having a longitudinal axis, with a packaging sheet. The device includes a packaging sheet dispenser which dispenses the packaging sheet to produce a body packaging by dispensing, on at least a portion of a longitudinal extent of the web roll, the packaging sheet. The packaging sheet dispenser is positioned to dispense the packaging sheet to form an acute angle between the lateral direction of the packaging sheet and the longitudinal axis. The packaging sheet dispenser is further arranged to dispense the packaging sheet to produce an end packaging having an axial projection on an end of the web roll. The packaging sheet dispenser is posited so that the lateral direction of the packaging sheet is substantially parallel to the longitudinal axis. During the production of the body packaging, the web roll migrates, which leads to problems in the subsequent placement of the face cover by the packing presses. To ease these problems, the packaging device further includes a packing press device that includes packing presses positioned to move parallel to the longitudinal axis. The packing presses are associated with end faces of the web roll and are independently positionable. The method includes forming an end packaging at a first end of the web roll that includes an axial projection, axially moving a packing plate toward the first end of the web roll, sensing the axial projection of the end packaging of the web roll, detecting placement of the packing plate relative to the axial projection, and pressing the packing plate against the first end of the web roll.
摘要:
A device and method for packaging a web roll with a packaging sheet dispenser that dispenses a packaging sheet at an adjustable angle relative to the radial direction of the web roll, that can be moved parallel to the axial direction of the web roll, and on which a supply roll of the packaging sheet is provided, along with a motor-drive for the web roll to be packaged.
摘要:
Device and method for packaging a material web roll, having a longitudinal axis, with a packaging sheet. The device includes a packaging sheet dispenser that dispenses the packaging sheet such that a lateral width of the packaging sheet forms an acute angle to the longitudinal axis. The device also includes a glue application station having a first glue application device composed of an operational gluing device and a second glue application device composed as an end gluing device. The method includes feeding the packaging sheet through a gluing station, applying at least one glue bead parallel to an edge of the packaging sheet, spraying glue onto at least a portion of the packaging sheet, and guiding the packaging sheet onto an outer surface of the material web roll.
摘要:
The packaging of a roll of material is achieved by coating at least one side of a packaging sheet with a water soluble adhesive. At least a portion of one side of the packaging sheet is wetted after the coating step and the packaging sheet is wound about the roll of material after the wetting step. The apparatus for packaging the roll of material includes an unwinding station, pulling equipment, a sheet severer, gluing equipment and a winding station. A packaging sheet is disposed in the unwinding station. The packaging sheet is coated on at least one surface with a water soluble adhesive. The pulling equipment has a device for pulling the packaging sheet from the unwinding station. The sheet severer has a device for severing the packaging sheet. The gluing equipment has a device for applying liquid to at least one surface of the packaging sheet. The winding station has a device for winding the packaging sheet about the roll of material.
