Problems solved by technology

[0020] A disadvantage of the known shaped members is that the half-shells, when interacting with the tube, cause the tube to rotate about its longitudinal axis (so called "tube twist")
Rotation of the tube about its longitudinal axis produces misalignment of the tube relative to the sealing and pressure elements and thus leads to defects in the packaging
In other words, rotation of the tube about its longitudinal axis may adversely affect the formation of the package

Embodiment Construction

[0048] figure 1 and figure 2 Shown is a packaging machine 1 for producing sealed packages 2 containing pourable food products (eg pasteurized or UHT milk, fruit juice, wine etc.) from a tube 14 of packaging material.

[0049] The tube 14 has a longitudinal axis A and is formed in a known manner by longitudinally folding and sealing a web of packaging material and is filled upstream with sterilized or aseptically processed food product.

[0050] In particular, the tube 14 passes through the first longitudinal edge 100 of the packaging material ( Image 6 ) superimposed on the second longitudinal edge 101 of the packaging material ( Image 6 ) and by sealing the first longitudinal edge 100 to the second longitudinal edge 101 to obtain a longitudinal seal 102 by means of sealing means (not shown).

[0051] The packaging machine 1 comprises a frame 3 defined by a first side wall 4 and a second side wall 5 and a first transverse wall 6 and a second transverse wall 7 mounted rig...

Abstract

A forming member for controlling the volume of packs (2) of pourable food products formed from a tube (14) of packaging material, said tube (14) comprising a longitudinal seal (102) obtained by superimposing a first longitudinal edge (100) of said packaging material on a second longitudinal edge (101) of said packaging material and by sealing said first longitudinal edge (100) to said second longitudinal edge (101), wherein said forming member comprises a forming half-shell (71) having a forming wall arrangement (77) adapted to interact with said tube (14), and wherein said forming member further comprises a pushing element (80) associated to said forming wall arrangement (77) to push part of said food product out of said tube (14), said pushing element (80) having a grove (83) intended toreceive at least a portion of said longitudinal seal (102) .

Description

technical field [0001] The present invention relates to a forming member for controlling the volume of a package of pourable food products formed from a tube of packaging material. Background technique [0002] It is well known that many liquid or pourable food products such as fruit juices, UHT (Ultra High Temperature Treated) milk, wine, tomato paste, etc. are sold in packages made of aseptic packaging materials. [0003] A typical example is the parallelepiped-shaped package for liquid or pourable food products known as Tetra Brik Aseptic (registered trademark), which is produced by folding and sealing laminated strip packaging material. The packaging material has a multilayer structure comprising a base layer (eg paper or mineral filled polypropylene) and layers of heat-sealable plastic material (eg polyethylene film) covering both sides of the base layer. [0004] In the case of aseptic packaging for long-term storage of products such as UHT milk, the packaging materia...
