Problems solved by technology

[0006] Furthermore, the heating power of the heating device cannot in principle be chosen arbitrarily high, since the thermal glue does not melt uniformly in this case and the thermal glue is in the edge region adjoining the wall of the thermal glue melting container The strip gets overheated and thus also "cracks"

Embodiment Construction

[0024] exist figure 1 with 2 The apparatus according to the invention for melting thermoglue granules for products of the tobacco processing industry, in particular for filters, into liquid thermoglue or also known as Hotmelt can be seen in isometric and sectional views, respectively. (hot melt adhesive). The device is a component of a superordinate plant in which the product is produced from raw materials in a continuous production process. The hot glue melted in this device is used, for example, to glue the edges of the filter paper and is applied in a thin film to one of the edges of the filter paper by means of a nozzle in an application device (not shown).

[0025] The device includes a storage container 20 configured in the form of a relatively large hot glue melting container with a volume of preferably 70 liters. In the storage container 20 is arranged a slider 17 that can be manipulated from the outside, the slider 17 has a pull rod 19 and a sliding plate 18, with ...

Abstract

Device for melting hot melt granulate for products of the tobacco processing industry, preferably a filter, comprises a hot melt melting tank (4) that is associated with a heating device (5), through which hot melt granules that are present in the hot melt melting tank, are melted, a storage tank (20), and a conveying device (11). The hot melt is continuously supplied from the storage tank to the hot melt-melting tank using conveying device and dosed.

Description

technical field [0001] The invention relates to a device for melting thermoglue pellets for products of the tobacco processing industry, in particular for filters. Background technique [0002] Hot glue (Hotmelt hot melt adhesive) is used in products of the tobacco processing industry for bonding filter paper and for fixing filter segments in multi-filters. The hot glue itself consists of a hydrophobic hot melt adhesive which is solid and non-adhesive at low temperatures (for example at normal temperature of 20 degrees Celsius) and made of a thermoplastic polymer. The thermal glue is delivered as pellets and is loaded as bulk goods into a thermal glue melting container in which the thermal glue is melted into a flowable mass. During the further production process, the flowable thermal glue is continuously fed by a pump to an application device, in which the thermal glue is applied, for example, to an edge zone of a filter paper. The filter rod with the filter paper bonded ...
