Embodiment Construction

[0042] figure 1 Shown in a schematic side view is a winder 1 for winding a fiber web 2 onto a mandrel 3 into a reel 4 shown only in dashed lines, in particular empty or partially Winding core. The fibrous web 2 may in particular be a fibrous web, such as a paper, cardboard or tissue web.

[0043] The winder 1 placed on the hall floor 100 comprises a carrying drum 5 , which is also called a pressure drum or a support roll in the professional field, and around which the fibrous web 2 is wound in sections, the carrying drum 5 is either rigidly supported , can either be moved along an imaginary horizontal line G indicated by a dotted line by means of a not shown slider device or a pressing device (double arrow P1 ) and generally driven by a not shown drive. Various bearings and types of movement for the carrier roller 5 are disclosed in particular in German laid-open publication DE 19807897 A1; the content of this publication with respect to the various types of bearings and mov...

Abstract

The invention relates to a winding machine (1) for winding a fibrous web (2), in particular a paper, board, or tissue web, onto a winding core (3), in particular an empty or partially wound winding core (3), to form a winding roll (4), comprising a support drum (5) around some areas of which the fibrous web (2) is wrapped and which has a preferably rubberized or coated surface (6) and which is supported in a stationary manner or preferably in a movable manner by means of a sliding device and which can form a winding nip (8) with the winding roll (4) in particular at times, comprising a reject container (10), which is arranged downstream of the support drum (5) in the running direction (L) of the fibrous web (2) and into which a feed strip (2.1) of the fibrous web (2) or the entire fibrous web (2) is lead away before a later feeding and subsequent winding onto the winding core (3); to form the winding roll (4), and comprising a scraper device (12) arranged in the lower area (11) of the support drum (5) and comprising at least one air knife (13) and a knife bearing (14). The winding machine (1) according to the invention is characterized in that the scraper device (12) is supported on a stationary foundation (15) independently of the bearing of the support drum (5) and that the scraper device (12) is supported on the stationary foundation (15) by means of at least two bearing points (L1, L2; L1 to L3; L1 to L4), at least one bearing point (L1, L2; L1 to L3; L1 to L4) being arranged in an area within the width (B) of the fibrous web (2).

Description

technical field [0001] The invention relates to a winding machine for winding a fibrous web, especially a paper, board or tissue web, onto a core, especially an empty or Partially wound core, the winding machine has a carrier drum, which is wound by the fibrous web in regions and has a preferably rubber-lined or coated surface, the carrier drum with Stationary or preferably movably supported by means of a slider arrangement, and in particular can sometimes form a winding gap with the reel; a waste container which is arranged in the direction of travel of the fiber web at the back of the carrier drum Afterwards, the updrawing strip (Aufführstreifen) of the fiber web or the entire fiber web is led out into the waste container before a later upturning and subsequent winding onto a mandrel to form a reel; and a doctor device, so The scraper arrangement is arranged in the lower region of the carrier drum and comprises at least one air scraper and a scraper support. [0002] The i...
