Problems solved by technology

[0025] The presence of this waterproof tape creates problems of reliability, both in terms of defects from fabric handling and resistance to use over time
Furthermore, the use of waterproofing strips leads to very high replacement costs and an extremely complex and burdensome possible replacement operation

Embodiment Construction

[0038] Fig. 4 is a schematic diagram of an apparatus or production line for continuous calendering of fabrics according to a first embodiment of the present invention. The calendering line is indicated in its entirety by the reference number 10 and comprises the following adjacent operating units:

[0039] - a moisture control unit or fabric conditioning unit 20, provided with means 27 for controlling the wetting of the surface and / or means 28 for impregnation with chemical products, and a pair of rollers 24-23, possibly heated, and The fabric is then placed between the pair of rollers;

[0040] - a calendering unit denoted by reference numeral 30, having two pairs of motor driven rollers stacked in a tower; and

[0041] - A possible drying and cooling device arranged downstream of the second calender unit 30 , which is not shown in the figure since it is conventional.

[0042] In the production line 10, the treated fabric 3 is rolled out of a corresponding feeder, drawn and...

Abstract

An apparatus for continuous calendering of fabrics comprises a first operating unit (20) with devices for surface moistening (27) of the fabric (3) and / or means for impregnation (28) of the fabric (3) with treatment liquids, and with cylinders (23, 24) for exerting on the fabric (3) a mechanical action of lateral pressing, and at least one second operating unit (30, 30a) for subjecting the fabric (3) to a condition of intense lateral pressing without the aid of a water-repellent belt.

Description

technical field [0001] The present invention relates to a method and apparatus for calendering of fabrics. [0002] In the field of textiles, the term "calendering" refers to a finishing process in which a fabric is subjected to thermal stretching in order to reduce its thickness, eliminate any possible wrinkles and create tendencies on at least one face ( tendentially) bright appearance. Background technique [0003] There are three calendering systems known in the art, namely: a) shoe calendering, b) roller calendering, and c) belt calendering, preferably for The different textile fields (synthetic fibers, vegetable fibers, and animal fibers) selectively use the above-mentioned calendering systems. [0004] Such as figure 1 Schematically shown in , in a first type of system a heated cylinder 1 rotates relative to a fixed recessed shoe 2 pressed against the cylinder itself, the fabric 3 to be treated is placed in between the concave shoe and the drum. Said technique is...
