Embodiment Construction

[0028] figure 1 A simplified longitudinal sectional view of the first embodiment of the bobbin spindle of the present invention. The bobbin spindle has a drive shaft 5 which is rotatably supported in a support 7 via a bearing 8 . The drive shaft 5 is connected to an electric drive at an end not shown in the figure. The end of the drive shaft 5 protruding relative to the support 7 is connected in a rotationally fixed manner to a hub 6 , which is connected to the hollow-cylindrical inner cylinder 3 . The hub 6 is preferably arranged in the central region of the inner cylinder 3 , wherein the overhanging section of the support 7 for supporting the drive shaft 5 projects into the open end of the inner cylinder 3 .

[0029] A hollow-cylindrical outer barrel 1 is spaced on the circumference of the inner barrel 3 and extends substantially along the entire length of the inner barrel 3 . The clamping device 2 is provided in the annular space 26 formed between the inner cylinder 3 an...

Abstract

The invention relates to a winding spindle for clamping a number of winding spools (10). The winding spindle is formed by an inner tube (3) and by an outer tube (1) that encircles the inner tube (3). The inner tube (3) is connected to a drive shaft (5). A clamping device (2) is situated between the inner tube (3) and the outer tube (1) and has a number of clamping elements (4), which can be extended through openings (9) of the outer tube (1) and are provided for tensioning the winding spools (10). According to the invention, the outer tube (1) situated on the periphery of the inner tube (3) is tensioned by a number of supporting means (12) that are interspaced between the inner tube (3) and the outer tube (1). To this end, the supporting means (12) produce a radially acting tension force between the inner tube (3) and the outer tube (1).

Description

technical field [0001] The invention relates to a bobbin spindle for clamping a plurality of bobbins for yarn in a winder. Background technique [0002] One such bobbin spindle is known from DE 19607916 A1. [0003] Such bobbin spindles are used in winders for winding especially freshly spun synthetic yarns into bobbins. For this purpose, a plurality of bobbins are mounted in succession on bobbin spindles arranged overhang in the winder. In order to clamp the bobbins, the bobbin spindle has a clamping device with a plurality of clamping elements that can be moved radially outwards. An annular space is formed between an outer cylinder and an inner cylinder for accommodating the clamping device. The inner cylinder is connected to a drive shaft in order to transmit the rotational movement. The outer cylinder is substantially positively connected to the inner cylinder, wherein the load-bearing capacity of the bobbin spindle is determined by the inner cylinder. The known bob...
