Problems solved by technology

[0020] As a result, the excess amount of label web material used to make each sleeve label—which ultimately leads to an increase in overall cost—remains as irregularities on the surface of the sleeve label that is finally applied to the corresponding container, which Generally considered undesirable by food industry companies, especially for aesthetic reasons

Embodiment Construction

[0038] figure 1 is shown for inserting the sleeve label 2 (see figure 2 and image 3 ) to a typical roll-fed labeling machine 1 that is applied to a corresponding item 3 (in particular a container, such as a bottle), each item ( Figure 1 to Figure 3 ) has a given longitudinal axis A, is bonded at the bottom by a bottom wall 4 substantially perpendicular to axis A, and has an upper neck 5 substantially coaxial with axis A.

[0039] The labeling machine 1 comprises conveyor means for bending and joining label web material parts into a tubular structure in order to form a sleeve label 2 and for inserting a container 3 into said sleeve label 2 .

[0040] In the preferred embodiment as shown, the conveying means comprises a carousel 7 mounted around a figure 1 The corresponding vertical axis B of the plane rotates continuously (in figure 1 in a counterclockwise direction).

[0041] The carousel 7 receives a series of unlabeled bottles 3 from an input wheel 8 cooperating with...

Abstract

The invention describes a method and unit for forming tubular lengths of web material and a labeling machine, the method comprising the steps of: a) winding the web material portion (2) into a tubular structure such that the wire overlapping the opposite vertical ends (34) of the web material (2); and b) engaging the overlapping ends (2) to secure the linear portion (2) of the web material into a sleeve structure; It is characterized in that the step b) also includes: c) heating the first zone (S') of the part (2) at a first temperature (T1), the end part (34) above the entire first zone overlapping; and d) heating a second zone (S" of said portion (2) adjacent to said first zone (S') at a second temperature (T2) lower than said first temperature (T1) ), the ends (34) of said label web material portion (2) overlap only over a part of said second zone (S").

Description

technical field [0001] The present invention relates to a method and unit for forming tubular lengths of web material. [0002] In particular, the present invention relates to a method and unit for forming and sealing portions of web material which, for labeling purposes, are given a tubular structure and are to be attached to articles, especially containers for pourable food products. , such as bottles, jars, etc.). [0003] Therefore, the following will specifically describe a labeling machine for handling web material for producing tubular lengths of said web material for use as labels. [0004] However, this is not intended to limit the scope of the appended claims, and the method disclosed herein for forming tubular sections of web material may be readily applied to other types of machines, such as machines for winding film-like materials Items of machines. Background technique [0005] Labeling machines are commonly used to apply labels to various containers. Most ...
