Embodiment Construction

[0031] In the manufacture of bottom bags, side gussets are formed at tube sections formed from flat webs glued together longitudinally or from tube fabrics. Subsequently, at one end of the pipe section, the so-called "factory end" 21, the clamped bottom surface is formed by turning the pipe end over approximately 180° along the fold line and joining / gluing it to the pipe wall, where the so-called "factory end" 21 "21 represents the bottom end and thus the bottom surface in the filled bag. In the bag 20 thus produced, the application of the reactivatable adhesive 23 is then carried out on the bag surface 24 near the open end of the bag 20 . This open end is called the "user end" 22 and remains open when the bag is delivered to the customer. The customer then fills the bag with product, typically a bulk material such as animal feed, and closes the bag after filling by reactivating the adhesive 23 and folding the open end of the bag 20 over the adhesive 23 . The filled bottom ...

Abstract

A device (1) for cooling an adhesive (23) applied to a surface (24) of a bag (20), comprising a transfer conveyor (2) and a cooling conveyor (4). The transfer conveyor (2) conveys the bags (20) to the cooling conveyor (4) at the transfer speed (3), and the cooling conveyor (4) conveys the bags (20) taken from the transfer conveyor at the cooling conveying speed (5) 20). The transfer speed (3) is higher than the cooling conveying speed (5), which is why the bags (20) are arranged on top of each other on the cooling conveyor. Due to this higher packing density, a longer residence time of the bags (20) in the cooling conveyor (4) is achieved, while at the same time a high flow rate of the bags (20) through the device is achieved.

Description

technical field [0001] The invention relates to a device for cooling adhesive applied to the surface of a bag, the device comprising a transfer conveyor and a cooling conveyor, wherein the transfer conveyor conveys the bags to the cooling conveyor at a transfer speed, and wherein the cooling The conveyor conveys the bags taken from the transfer conveyor at the cooling conveying speed. Background technique [0002] There is an increasing market demand for printable and consistent high-quality bags for the consumer sector. Gusseted bags are especially needed, eg bottom bags made of plastic material, especially plastic fabric (composite material), since this material has a very high tensile strength compared to bags made of paper. [0003] Especially in the field of animal feed, the discharged bulk material not only poses a problem in the form of contamination, but also attracts vermin, which can lead to hygiene problems. [0004] The manufacture of gusseted packages made of ...
