Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an endless carpet that operates as a support member or drive mechanism for use in machines such as fulling machines for wet-processing knitted fabrics such as woolen fabrics, as well as washing and dyeing machines.

Italian patent applications filed in the name of the applicant (Patent Application No. 25669A/80 filed on July 21, 1980 and Patent Application No. 31410A/80 filed on December 29, 1978)
Endless carpets shaped like a ring are known, as shown in No. 78). Endless carpets of this type are attached to two or more cylindrical members, at least one of which is driven. However, especially in high-speed machines, wet knitted fabrics such as woolen fabrics adhere closely to the endless carpet at the return point of the endless carpet, which hinders the normal operation of the machine and damages the knitted fabrics, so the operating speed of the machine is reduced. I realized that I needed to.

The present invention solves this problem by giving the endless carpet a special shape. This shape is characterized in that a plurality of protrusions are provided spaced apart from each other on the outer surface of the endless carpet.

Preferably, these spaced apart projections are ribs extending laterally on the endless carpet. In this way, the knitted fabric is at least partially lifted,
Since air can enter between the endless carpet and the knitted fabric at the outlet of the endless carpet, the above-mentioned close contact between the endless carpet and the knitted fabric can be avoided.

Additionally, conventional endless carpets have the disadvantage that even when the cylindrical member is slightly crowned, it sometimes displaces laterally when rotated at high speeds. This type of drawback can be overcome by providing a plurality of longitudinal ribs on the underside or underside of the endless carpet, these ribs being guided in corresponding grooves formed in the cylindrical member. be done.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that what is shown in the accompanying drawings is merely an example.

It should be noted that the present invention relates to a special carpet used in a specific machine, and does not relate to a machine to which this type of carpet is installed. Therefore, the machines partially shown in the accompanying drawings are not intended to limit the invention in any way, and detailed descriptions of the machines will be omitted.

BRIEF DESCRIPTION OF THE DRAWINGS The machine shown by way of example in the accompanying drawings is for the wet treatment (for example washing or fulling) of textiles which are interconnected at both ends in a closed ring or loop. The knitted fabric passes through the aqueous mass in the machine's tub member.
It is moved or driven in the direction of arrow A by the flexible carpet 2 passing through the cylindrical members 3, 4, 5 of the book. The first two of these cylindrical members are idle, and the last one is driven by motor unit MA.

Idle cylindrical member 6 at the location of the drive cylindrical member 5
is pressing the knitted fabric 1. At this time, knitted fabric 1
passes through the gap K between the idle cylindrical member 6 and the carpet 2. Then, pressure is applied by the pneumatic cylinder 7 which is coupled or pivotally supported by the fixed part 8 and the frame 9 through a pin joint. The frame 9 supports the pressure roller (idler cylindrical member) 6,
It is coupled or pivoted to another fixed location at a location 10 by means of a pin joint.

In order to prevent the knitted fabric coming out of the above-mentioned gap from remaining in close contact with the carpet, in the present invention, protrusions are formed on the outer surface of the carpet in a somewhat regular manner in a direction transverse to the direction of movement. They are set at intervals. In the embodiment of the accompanying drawings, the projections are shown as transverse ribs 11 of the same length as the width of the carpet. This will allow air to get under the knitted fabric and encourage it to move away from the carpet, so these ribs will partially lift the knitted fabric out of the plane of the carpet, causing the fabric to gape. When coming out of K, it does not come into close contact with the carpet.

When operating at high speeds, the carpet tends to displace laterally, so croning of the cylindrical members 3, 4, 5 is not sufficient to ensure that the carpet remains in place. . For this purpose, the underside or underside of the carpet may be provided with one or more longitudinal ribs 12, which are guided in corresponding grooves 13 formed in the cylindrical members 3, 4, 5. These ribs are preferably trapezoidal.
