Abstract

This invention relates to a device that fastens a support (2) of a drafting device to a holding rod (3) of a spinning machine, wherein an upper roller bearing and a pressurizing arm (1) are mounted on the support (2) in the mode of pivoted mounting. The device has a double-arm lever (12) that is capable of pivoting surrounding a pivotal shaft (14) parallel to the holding rod (3) in the axial direction. The lever (12) comprises a first lever arm (15) that may be jointed with a concave section (3) mounted in the holding rod (3) so as to fasten the roller bearing and the support (2) of the pressurizing arm (1); the lever further comprises a second lever arm (16), on which a device (13) is mounted so as to position the lever (12) on the transporting and assembling position or the fastening position.

Description

technical field [0001] The invention relates to a device for fastening a support of a drafting device. Background technique [0002] Drafting device for a spinning machine comprising a top roller support and pressing arm pivotally mounted on a support, the top roller support and pressing arm being detachably fixed to a holding bar by means of a device superior. Usually, several top roller supports and pressing arms of the drafting device are arranged side by side on a holding bar arranged along the machine length of the spinning machine. [0003] According to a very simple embodiment of a device for fastening a support, as disclosed in DE-AS 1 133 289, a support consisting of two plates is arranged to be fixed in position by means of fastening screws on on the retaining rod in such a way that the retaining rod has a hole for arranging the support, into which a fastening screw engages. This has the disadvantage that the hole in the retaining rod can be damaged due to the t...
