Problems solved by technology

However, this solution has a high complexity and thus relatively high cost
Furthermore, it has been found that the stratified flow leads to an undesirably high thermal insulation effect, which negatively affects the effective heat output from the weld seam of the material web

Embodiment Construction

[0044] Figure 1a A very schematic longitudinal section view of an apparatus 10 for producing pipe bodies is shown. The device 10 comprises an elongated mandrel 2 around which a material web 1, here configured as a plastic laminate, can be deformed into a substantially circular tubular piece 3 by means of a forming device 7, here configured as a forming belt, , the tubular piece can then be welded to itself using a welding tool 4, in particular an induction welding device. Using the welding device 4 , the edge regions of the incoming material webs that abut against each other or overlap each other in the welding zone are welded to one another and produce a weld seam that extends or runs along the mandrel 2 . In the exemplary embodiment shown, a pressing device 5 is arranged downstream of the welding device 4 in the transport direction A of the material web 1 , which press device exerts a settable contact pressure on the newly welded tubular part 3 . A cooling device 6 for coo...

Abstract

The invention relates to a device (10) for producing a tube body for a packaging tube made of a material web (1), and the device (1) comprises a mandrel (2) which extends in the axial direction and around which the material web (1) can be deformed in order to produce a tube (3); a welding device (4) for welding the material web (1), preferably in a welding zone (23) of the material web (1) and along a transport direction (A) of the material web (1); a cooling device (6) downstream of the welding device (4) for cooling the welded material web (1), wherein the cooling device (6) has a cooling body (20a, 20b) extending in the transport direction (A) of the material web (1), and the cooling body has a cooling surface (6a) which faces the material web (1), in particular the welding zone (23) ofthe material web (1), or which can be driven around and is assigned to the material web (11); and a swirl zone (9) arranged therein, which is designed to provide a swirled gas volume flow (V) betweenthe surface (1a, 11a, 12a) to be cooled and the cooling body (20a, 20b).

Description

technical field [0001] The invention relates to a device and a method for producing a tube body for a packaging tube made of a web of weldable material. In particular, the invention relates to such apparatus and methods with improved cooling means. Background technique [0002] Apparatus for producing pipe bodies are known from the prior art. These devices generally comprise: a mandrel extending in the axial direction about which a single-layer or multi-layer material web, such as a plastic laminate web, can be deformed for the manufacture of tubular parts; and a material web for welding deformation Welding equipment, such as induction welding equipment. [0003] When using a material web with at least one metal layer, for example an aluminum layer, the deformed material web can be welded by inductively heating the metal layer and subsequently allowed to cool. Furthermore, it is also known, especially when using material webs made of plastic laminates, that the device has...
