Embodiment Construction

[0028] reference Figure 1 , marker 1 generally indicates a packaging component, which is configured to form, seal and fold a plurality of semi-finished packages containing a dumpable product (preferably dumpable food) starting from the packaging material tube (not shown) 2.

[0029] The packaging material has a multi-layer structure (not shown) and comprises a layer of fiber material (e.g., paper), two sides are covered with a heat-sealed plastic material (e.g., polyethylene) layer.

[0030] In the case of a sterile package 2 for long-term storage of the product (e.g., UHT milk), the packaging material further comprises a gas and light-blocking material layer, such as aluminum foil or vinyl alcohol (EVOH) film, which is stacked on a layer of heat-sealed plastic material, and then covered with another layer of heat-sealed plastic material, which forms the inner surface of the package 2 that finally contacts the dumpable product.

[0031]The tube is formed in a known manner by lon...

Abstract

There is described an infeed unit (5, 5 ') configured to feed a sealed semi-finished product pack (2) containing pourable product into a folding unit (4) adapted to fold the pack (2) to obtain a folded package, the infeed unit (5, 5') comprising: a conveying device (6) having at least one carrier element (7) configured to advance the pack (2) from an inlet region (I) of the infeed unit (5, 5 ') to an outlet region (O) of the infeed unit (5, 5'); and a feed screw device (20) arranged at the exit region (O) and configured to receive the bale (2) from the conveying device (6), to advance the bale (2) along a braking path (Q) and to feed the bale (2) into the folding unit (4); the feed screw arrangement (20) is configured to reduce the speed of the bag (2) along the braking path (Q).

Description

Technical field [0001] The present invention relates to an infeed unit configured to receive a sealed pillow pack containing a dumpable product (preferably a dumpable food) from a forming unit configured to form a packet, and the pillow pack is fed into a folding unit configured to fold a pillow pack to obtain a fully folded finished package. Background [0002] As we all know, fruit juices, UHT (ultra-high temperature processed) milk, wine, ketchup and many other dumpable foods are sold in packaging made of sterile packaging materials. [0003] A typical example is the parallelhexahedral packaging used for dumpable food products, called Tetra Brik Aseptic (registered trademark), which is made by folding and sealing the laminate coil of the packaging material. The packaging material has a multi-layer structure, the multi-layer structure comprises a base layer, which is made of paper, for example, and the two sides are covered with a layer of heat-sealed plastic (e.g., polyethyle...
