Description

Continuous treatment device a tricot panel to relieve internal tension

The present invention relates to an apparatus for the continuous treatment of a tricot web for the reduction of internal tensions, with this treatment being the purpose the aim is to ensure that the jersey has absolute stability in terms of dimensions, both in length and also received in width. .

It is known that every jersey, no matter if he comes from the machine or from the bleach, or whether it has undergone a dyeing or finishing treatment that internal uniformity or stability with regard to its external dimensions is lacking, mainly because of the tension placed on the fabric during the Knitting or dyeing or needlework,

Are such tricot fabrics or articles made from them Tricot fabrics are made washed so are common Determine shrinkage, which is up to 2o% of the original dimensions reachable.

In order to use a tricot made of hydrophilic material (e.g. wool or cotton) to reduce internal tensions, it has already been proposed to use the articles made from them moisten or treat with steam »

One known beneficial method is to . Place the tricot webs first laid in gaps on a transport element, then this web laid in gaps on transfer a second means of transport, which is below the first transport element is, this transfer of the Tricot web is carried out from the first to the second transport element so that afterwards the folds in reverse Lay on the second transport element.

During this pretreatment, the pits are laid Railway exposed to a strong oscillation of higher frequency, with water vapor during this oscillation or hot air. acts on the jersey panel.

To carry out this pretreatment, a device was

proposed device, which consists of a chamber ₉ soft water vapor or hot air at low speed

There are also devices on this chamber provided to place the entering tricot web in folds. In addition, a group of different conveyor belts is provided, which lie on top of one another and behind the fold layer are arranged and with which the tricot web is transferred in the folded state to another conveyor belt which another conveyor belt is housed with the part of the tricot web exposed to its own weight This known device is particularly distinguished by the fact that at the end of the conveyor belt * on which the tricot panel rests, another pleat is provided for the jersey web and that at least one of these conveyor belts - preferably the one at the end of the Conveyor belt group or behind the second creamer - is provided with means through which the folded tricot web can be set in rapid oscillations.

These methods and the devices described in more detail below require several - * Conveyor belts. In fact, they can move from the vibrating bars conveyor cloths set in rapid vibrations no longer than one meter, mainly because of to avoid resonance with the natural frequency of the conveyor belt, causing poor guidance of the jersey web and the phenomenon of vibration of the oscillating bars could disturb.

Another known device consists of a pleat for the tricot panel and a means of transport, which runs over two rollers and also has another roller to regulate the tension - a rigid one and fixed table is located below the support part of the conveyor belt and is supported by a suitable one Vibration generator set in vibration.

The greatest disadvantage of such a device is that a sufficiently strong vibration generator is provided must be in order to set the relatively large mass of the table in sufficiently strong vibration so that the inner Tensions in the jersey panel can be relieved.

The present invention overcomes these prior art inconveniences and N _a chteile and looks mainly a device from which the transport of the tricot web vereinfacht.Ferner the inventive apparatus may be better adapted to the different operations in the fabrication of the jersey and installed much easier.

For this purpose is a device for continuous Treatment of a jersey panel to relieve internal tension provided, with appropriate means for the treatment of the Tricot panel with steam or hot air, as well as a fold layer and at least one conveyor belt carrying the folded tricot web is provided, the conveyor belt from the fold

Folders turned away and learn to see through a conflict t on the underside of which there is at least one vibrating rod - ' is provided, which the tricot web transversely to the intermediate layer element can vibrate.

This device is characterized in that the Zwisehentragelement consists of a cloth, which on the one hand is stretched and immobile with respect to the conveyor belt and on the other hand eliminates an actively usable length whose |

own resonance frequency is greater than the oscillation frequency of the vibrating rods.

Further details emerge from the following description, which is only intended to represent an exemplary embodiment, but not a limitation of the invention, as well as from the accompanying drawing, in which an embodiment of the device according to the present invention. Invention is shown schematically . ■ '■.

The device according to the invention consists of one or several slings, 1, preferably made of metal mesh, which are arranged one behind the other on fixed rollers 2,3,4. One of these roles, preferably the role 3, is with a known system for regulating the tension provided, which is not shown in the drawing, but was indicated schematically by an arrow. Below the Support part 1a of each metallic sling 1 in the form

009882/1557 _ ₆ ._

An endless conveyor belt vibrating rods 5 are arranged, by means of which the support part 1a can be set in vibration by the vibrating rods transmitting the vibrations of increased frequency to the conveyor belt. In addition, the metallic slings 1 have an active length, namely that between the carrier rollers 2 4 and 4, whose own resonance frequency is greater than the oscillation frequency of the vibrating rods 5. The atomizers 6, which emit steam or hot air, are also arranged under the support part 1a of each metallic sling 1, the slings having openings for this purpose, to allow the water vapor to bind into the tricot web 7. The atomizers 6 are preferably arranged on both sides of the vibrating rods. The tricot web 7, which comes from a supply roll, a container or a plate (all not shown), goes in the unfolded state between two transport rollers 8 through which in one in itself known folders 9 are provided for the tricot web 7, so that the tricot web 7, already in folds, falls down onto a conveyor belt Io. The conveyor belt Io is stranded with openings and lies directly above and on the metallic carrying cloths 1, so that the vibrations of the vibrating rod © 5 are transferred to the tricot web 7. The conveyor belt Io is carried on the one hand by the rollers 11 to 14 and is set in a left-to-right movement ₈ that is, in a movement ^ in which the tricot web 7 is pulled off the folders 9, this movement s, B, causing rollers 12 and 14 which rotate in the direction of the arrow and which rotate with a

Drive motor are connected, which is not shown here. On the other hand, the conveyor belt Io has one Support part, which is on the upper support parts 1a of the metallic Sling 1 slides. Based on these facts, the Conveyor belt Io very good properties in terms of Friction, behavior in moisture and heat and it is easy enough for the transmission of mechanical vibrations also not to disturb the jersey panel 7.

: '■■ ■■'; I.

With this conveyor belt Io it is therefore possible to move from one metallic sling 1 to another without difficulty Go over baby wrap, regardless of whether the jersey panel is flat lies or is laid in folds, and then the tricot panel take off under the best conditions at the end of the device. The speeds of this conveyor belt Io and the rollers 11-14 can be set, creating a speed control can be combined with the regulation of the feed of the trijot track 7 and its treatment time.

It is of course easily possible, the atomizer 6 as well to be arranged over the tricot web 7 or to omit it entirely if the entire device consists of a single metallic one Sling 1 consists, which in a with steam or hot air filled chamber is housed. There is also no more necessary, a conveyor belt Io and a metal mesh 1a with openings to be provided as the openings of the metal mesh without further allow penetration with steam or hot air.
