The invention discloses a contraction tunnel (18) with a control and / or regulation device (22) and at least one sensor system (24). The sensor system can provide the control and / or regulation device (22) with information about the corresponding result of the contraction. A method (18) of operating such a shrink tunnel is also disclosed. According to the invention, the control and / or regulation device (22) is designed to utilize the provided information by means of machine learning, and the contraction tunnel (18) can be controlled and / or regulated in consideration of the information thus utilized.

A packaging system (1) for articles such as beverage containers or the like is disclosed. The packaging system (1) comprises a shrink tunnel (10) which is designed to produce packages by shrinking thermoplastic packaging material onto sets of articles. The packaging system (1) further comprises at least one buffer (4, 5) into which packages produced by the shrink tunnel (10) can be fed. According to the invention, the at least one buffer (4, 5) is formed by at least one spiral conveyor (6, 7).

An apparatus for shrinking film onto products moving along a conveyance path includes an elongated steam chamber shaped to form a shrink tunnel through which the conveyance path extends, wherein tunnel side surface portions of the elongated steam chamber bound the path at least in tunnel regions above a plane of the conveyance path and the tunnel side surface portions are heated by steam within the elongated steam chamber and the tunnel side surface portions thereby radiate heat into the shrink tunnel. At least one steam header is positioned within the shrink tunnel and extending along at least part of a length of the shrink tunnel, the steam header including a plurality of steam ejection orifices for ejecting steam into the shrink tunnel. At least one steam flow path feeds steam from an output of the elongated steam chamber to an input of the at least one steam header.

The present invention relates to a hot air shrink tunnel (10) of a heat shrink device for heat shrinking shrink labels for packaging products, the hot air shrink tunnel surrounding a conveying path of the products. The hot air shrink tunnel includes a humid air zone (1, 2) and a dry air zone (3, 4) arranged in this order in the conveying direction of the products passing through the hot air shrink tunnel (10), the humid air zone (1, 2) includes a heating means for heating the air flowing in the humid air zone (1, 2) and a water diffusion means for diffusing an amount of water in the air flowing in the humid air zone (1, 2) to generate an air-steam mixture, and the dry air zone (3, 4) includes a heating means for heating the air flowing in the dry air zone (3, 4).

A packaging machine (10) and a method for operating the same are disclosed. The packaging machine (10) comprises a shrink tunnel (12) and a grouping station (22) arranged downstream of the shrink tunnel (12) and coupled to the shrink tunnel (12) by a conveyor section (24) for regrouping packaging units (14) transported from the shrink tunnel (12) via the conveyor section (24). A buffer section (26) associated with the at least one conveyor section (24) and equipped with a horizontal conveyor device can be connected to the conveyor section (24) via at least one horizontal or vertical branch. The buffer section (26) enables packaging units (14) to be removed from the conveyor section (24) or packaging units (14) located on the buffer section (26) to be returned to the conveyor section (24).

A shrink tunnel (10) with an inlet opening (22), with a temperature-controlled interior (40), with an outlet opening (24) and with at least one transport section (26) leading between the inlet opening (22) and the outlet opening (24) through the interior (40) of the shrink tunnel (10) for the at least two-lane transport of temperature-controlled packaged goods (12) is disclosed. Furthermore, a method for operating a shrink tunnel (10) is disclosed, which comprises a temperature-controlled interior (40) through which at least one transport section (26) for transporting temperature-controlled unit loads (12) passes on at least two parallel tracks (32), which transport section (26) connects an inlet opening (22) and an outlet opening (24) of the shrink tunnel (10).
