Drying machine for fabrics and method for drying fabrics

Abstract

Drying machine for continuous fabrics, comprising: A) an initial accumulation station in which the fabric is adapted to enter the machine from the outside continuously at a first speed and in an open width; and an end accumulation station, The fabric is adapted to leave from the end gathering station continuously and in an open width at the same speed as the first speed towards the outside of the machine; B) a drying tunnel between the starting and ending gathering stations, open width The fabric is suitable for passing through the drying tunnel; C) for causing the fabric to move alternately between the two gathering stations and inside the tunnel at a second moving speed that is greater than the first speed. The alternating moving device is used to alternately collect fabrics on the two gathering stations; wherein the alternating moving device includes a bell-shaped piece and a rotating roller arranged inside the bell-shaped piece, and the roller is suitable for The direction of rotation is reversed, the roller has an inner cavity and a cylindrical surface provided with a plurality of channels toward the inner cavity, and a cylindrical surface of the roller and the inner surface of the bell-shaped member define a at least a part of the drying tunnel, the fabric being arranged in an open width on the cylindrical surface of the roller, the fabric being freely arranged on the roller, in the tunnel and in the accumulation station; D) A hot air system, the hot air system comprising an air heating station operatively connected to the drying tunnel on the conveying side, the hot air system further comprising means for moving from the inside of the roller towards a suction duct for extracting air from an area outside the tunnel such that hot air passes through the tunnel and enters the roller through the channel in such a way that it impinges on the fabric arranged on the roller and at least partially dries the fabric, and out of the roller to the outside of the tunnel.

Description

technical field [0001] The invention relates to the field of industrial systems for the production and treatment of fabrics. More particularly, the present invention relates to a drying machine for fabrics and a method of drying fabrics. More specifically, the machine is suitable for fabrics that enter the machine continuously and exit the machine continuously, so that the machine can be used in continuous production / processing lines where the fabric passes continuously between work stations. [0002] The fabric is intended to be arranged in an open width inside the machine and may be open (i.e. extending in a single layer transversely to the feed direction of the fabric with two transverse ends free) or tubular (i.e. closed in cross-section into ring, without ends, i.e. two transverse ends joined together). Furthermore, the fabric is intended to be "free-standing" in the machine, ie it is neither guided laterally nor constrained laterally by clamps, pins, etc. on the convey...
