Embodiment Construction

[0028] The preferred embodiment of the device for unwinding a wound web, schematically illustrated in FIG. 1, is preferably used in the paper processing industry for the paper web to be pulled out from a wound web for further processing, and it has a frame in which The figure shows only partially schematically two spaced apart vertical columns 2 . Usually four such vertical uprights are used to form the machine frame, which are connected to one another by longitudinal and transverse beams, also not shown in the figures.

[0029] As shown in the figure, a transverse beam 4 is arranged between two spaced apart vertical columns 2, which extends substantially horizontally. The crossbeam 4 is supported vertically displaceably in the illustrated embodiment on the columns 2 via its two lateral ends 4a, wherein in the illustrated embodiment the support is via a guide rail acting in the vertical direction The system configuration is shown schematically in the drawing and indicated by ...

Abstract

An unwinding device for wound rolls includes a bearing element (4), a first support element and a second support element (10) mounted on the bearing element (4). The first and second support elements (10) are adapted to rotatably hold the wound roll on opposed sides. The first support element and the second support element (10) are movable along the bearing element with respect to one another, such that a distance between the first support element and the second support element (10) changes. The unwinding device also includes a drive mechanism adapted to move the first support element and thesecond support element (10) along the bearing element (4). The drive mechanism includes a tensioner (2) movable along the bearing element (4), and a first engagement member (26) disposed on at least one support element (10). The first engagement member is adapted to releasably lock the first support element (10) to the tensioner (20).

Description

technical field [0001] The invention relates to an uncoiling device for winding coils, which has a support part, two support parts arranged on the support part for rotatably fixing the winding coil on both sides, wherein the two support parts are along The support part is mounted displaceably in such a way that the mutual distance between the two support parts changes during a relative movement, and also has a drive for moving the two support parts along the support part. Background technique [0002] Material webs, especially paper webs, are typically supplied and stored in the paper converting industry in the form of large, heavy wound rolls. When processing such a material web on a corresponding device, the web is drawn off from the wound coil. These processing plants are therefore equipped with corresponding unwinding devices, in which the wound coil is mounted rotatably on both sides on two support parts arranged on the support part. In this case, the winding web is u...
