Embodiment Construction

[0017] refer to figure 1 , The finishing device 1 of the present invention comprises a compacting unit 2 and a steaming unit 3 arranged downstream of the compacting unit 2, the steaming unit 3 having an autoclave 4 of closed type (indicated by dashed lines in the figure).

[0018] The web 5 to be treated is supplied to the compacting unit 2 from a container 6 arranged upstream of the compacting unit 2 .

[0019] The compacting unit 2 comprises a compacting device 7 provided, for example, with at least one pair of counter-rotating cylinders 7a, 7b adapted to reduce the thickness of the fabric 5 in a predetermined manner. As is known, one or more cylinders of the compaction unit 2 are heated in order to be able to stabilize the reduced thickness of the fabric 5 .

[0020] Such as figure 2 As an alternative to the counter-rotating cylinders 7a, 7b shown in the variant of the trimming device 1 shown in , the pressing device 7 may comprise a belt 7c supported by a plurality of r...

Abstract

The present invention relates to a repairing device (1) comprising a compressing unit (2) and a steaming unit (3), wherein the compressing unit (2) is suitable for reducing the thickness of a textile (5) to be processed, the steaming unit (3) is arranged at a lower course of the compressing unit (2) and comprises a closed type autoclave (4). The repairing device (1) also comprises a winding unit (8) which is arranged tightly closing to the lower course of the compressing unit (2) and suitable for making the textile (5) directly be winded on a steaming cylinder (9) from the compressing unit (2). The present invention also relates to a repairing method comprising a textile (5) compressing step and a steaming step, wherein after the textile (5) compressing step, the textile (5) is winded on the steaming cylinder (9).

Description

technical field [0001] The present invention relates to a device and a method for finishing fabrics, and in particular to such a finishing device and method in which the fabric is compacted and subsequently steamed in an autoclave of the closed type. Background technique [0002] Steaming treatment is known to improve the quality of fabrics in terms of gloss and hand and to render them very high dimensional stability, which is particularly important for subsequent packaging operations. [0003] When the steaming process is carried out in a closed autoclave, the fabric, together with a suitably stretched special technical tape, is wrapped around a steaming cylinder with a hollow core and multiple through holes. The roll of fabric thus prepared is then inserted into a tightly sealed autoclave, enabling the fabric to be treated by steam under pressure. During the treatment, steam passes through the layers of the fabrics, reducing their thickness due to the pressure exerted by...
