Description

Machine for stripping, unrolling, measuring, cutting and rerolling webs

Description:

The present invention relates to a machine for measuring, cutting and rewinding webs of material stored in rolls, in particular textile flooring and PVC floor coverings, which are hung horizontally in holders, presented in a special unwinding device or held in some other way.

Devices for rolling, measuring and winding up webs of material are already known, in which the webs are pulled off the roll by electrically driven pairs of rollers. They pass through a measuring device and are then rolled up again by pairs of rollers or a roller conveyor.

Some of these facilities are equipped with devices that enable the rolling of the goods beginnings mechanically, whereby the equipment built-up molded parts or by appropriately shaped Swivel parts of the beginning of the goods are formed.

Description

However, the known facilities have various disadvantages. For example, attached molded parts are not very practical and hindering, shaped swivel parts only partially enable the desired small diameter of the beginning of the product, so that manual intervention is regularly necessary.

According to the present invention, a machine is provided for pulling, measuring, cutting, separating and rerolling webs of material, in particular PVC flooring and textile floor coverings, in which the above-mentioned and other disadvantages are eliminated. Such a machine according to the invention is characterized in that the machine has a pair of conveyor rollers between which the web of material is guided in such a way that the upper roller (1) cannot be lifted by the web of material, but at the same time the clamping effect of the pair of rollers to the main transport roller (2) is increased.

Furthermore, a measuring device is arranged below the web in the direction of travel of the web, whereby a measuring wheel is driven by pressing it against the material to be measured and drives the measuring system.

for cutting the material web lengthwise, which has a drive motor that is independent of the winding drive of the machine, whereby the knife is pulled over the machine table by a drag device (k).

Furthermore, a similar cutting machine (5) is mounted in the direction of web travel at an angle of 90° to the aforementioned machine (3), which is connected to a The conveyor element (S) can be operated from the operator's station and can be moved continuously over the entire width of the table. The reference point is the web of material, which is scanned by an edge guide connected to the conveyor element (6).

Description

When leaving the machine table (7), the web of material is guided downwards and preformed and guided through the semi-circular winding trough (8), with a molded part O) that can be pivoted into the horizontal position being mounted at the end of the trough (8). This pivotable molded part O) in turn consists of pivotable sub-elements (10), with these sub-elements each rotating about a pivot point in such a way that the material is guided in a direction perpendicular to the axis of rotation ( R ) .

A circular chamber is created in which the beginning of the material web is formed with a small or optionally larger diameter as required. The weight of the molded parts, which are manually or motor-driven inwards or outwards, is held by spring forces acting against the direction of movement, whereby the molded parts are connected to one another and to the springs via a balance shaft (11).

The adjustment of the sectional elements (10) can be carried out mechanically, electromechanically or pneumatically, so that the respective position of the molded part (S) and the sectional element (10) results in the shape corresponding to the roll diameter of the web of material, so that this lies equally well on the transport rollers of the trough (8) as well as on the transport rollers of the molded parts (O) and sectional elements (10).
