Embodiment Construction

[0027] In this exemplary embodiment, the device 1 for drying a yarn sheet 2 has four drying cylinders 3 , 4 , 5 , 6 . The yarn sheet 2 is guided through the device 1 in such a way that it wraps around each drying drum at the largest possible wrap angle. In this embodiment, the yarn sheet 2 encircles each of the drying cylinders 3-6 by at least 180°. The yarn sheet 2 is placed here on the surface of the corresponding drying cylinder 3 - 6 . The drying cylinder 3 - 6 is heated in a manner not shown here, ie the surface of the drying cylinder 3 - 6 has an elevated temperature.

[0028] The increased temperature of the surface of the drying cylinders 3 - 6 causes the moisture contained in the yarn sheets 2 to evaporate, and the yarn sheets 2 are thus dried during movement through the device 1 .

[0029] Each drying drum 3 - 6 has its own rotary drive 7 , 8 , 9 , 10 . The rotary drive mechanism 7-10 is connected to a control mechanism 11 which activates the rotary drive mechanis...

Abstract

The present invention relates to an apparatus and method for drying sheets of yarn. A device (1) for drying a sheet of yarn (2) is described, having an inlet, an outlet and at least two drying cylinders between the inlet and the outlet, wherein the yarn between the inlet and the outlet The sheet path encircles the drying cylinder over part of the circumference of the drying cylinder. It is desirable to keep the yarn load small while drying. Provision is made for this that each drying cylinder has its own rotary drive and that a control mechanism is provided which activates the rotary drive individually.

Description

technical field [0001] The invention relates to a device for drying a sheet having an inlet, an outlet and at least two drying cylinders between said inlet and said outlet, wherein the path of the sheet between said inlet and said outlet is in A portion of the peripheral surface of the drying cylinder surrounds the drying cylinder. [0002] Furthermore, the invention relates to a method for drying a yarn sheet, wherein the yarn sheet is guided through a drying device having at least two drying cylinders between an inlet and an outlet, wherein the yarn sheet partially surrounds the drying cylinders. Background technique [0003] The yarns of the sheet must usually be pretreated before being further processed into textile fabrics. An example of such a pretreatment is so-called sizing, in which a size solution is applied to the yarn. The size is applied to the yarn several times by means of an aqueous solution, so that the yarn sheet must be dried before further processing. ...
