Embodiment Construction

[0029] Hereinafter, "longitudinal axis" means the central axis of the web roll about which the packaging material or product is wound on the web roll being packaged and which is parallel to the longitudinal direction of the packaging material or product being packaged on the web roll. direction cross.

[0030]In this specification, unless otherwise stated, the web being packaged and the roll of packaging material are considered to be in a horizontal position, and the angles and relative positions between their longitudinal axes are relative to each other when viewed from above. angle formed by each other. For example, the roll of packaging material may be in an inclined position with respect to a horizontal or vertical plane. The most common situation is that although the longitudinal axes of the different packaging material rolls and the web rolls being packaged are horizontal, there is a difference in height between them, so that the packaging material can be placed under t...

Abstract

A method and arrangement for leading the wrapping material of rolls of wrapping material in a packing machine from a roll of wrapping material to a roll being packed in the wrapper of paper, board and other fibrous materials comprises at least a wrapping station (2) and at least one place (4) for the roll of wrapping material. For handling the wrapper the arrangement includes elements (9) for leading a packing wrapper (21) from a roll of wrapping material (4,5-8) to a roll being packed at the wrapping station (2). Furthermore in the arrangement, there is at least one place (5-8) for the roll of wrapping material which is located so that the longitudinal axis of the roll of wrapping material (5-8) placed in it forms an angle with the longitudinal axis of the roll being packed when unwrapping the wrapper (21). For leading the wrapper (21) to the roll being packed, there is arranged at least one creasing element (9).

Description

technical field [0001] The present invention relates to a method for guiding wrap in a wrapped roll from a roll of wrapping material when wrapping rolls of paper, cardboard and other fibrous webs in a packaging machine The method to the web being packaged. [0002] The invention also relates to a device for carrying out the method. Background technique [0003] A number of different roll packing methods are known. Most commonly, the paper or cardboard web roll is still packed within a strong wrapping paper around which the roll is wrapped. Inner and outer end labels are provided at the ends of the web to mechanically protect the web and to protect the web from external impacts. Theoretically, the packing wrap can be wound around the packaging web in three ways. If there is a sufficient variety of rolls of packaging material available in different widths, only one wrapping layer covering the entire length of the web is wound on the web or group of rolls being packaged. T...
