ABSTRACT:
A tine for fixing to a cylindrical carrier tube of a reel, in addition to a tine assembly comprising a carrier tube and a tine. The tine (8) comprises the following: a coil spring section (10) with at least one convolution wound about a coil spring axis (11) as far as a screw line; an engagement section (14), which is immediately adjacent to and leads continuously from the first end (12) of the convolution of the coil spring section (10), terminating in a free end (15); a fixing section (16), which is immediately adjacent to the second end (13) of the convolution and whose free end is bent to form an eyelet (17) with a through opening (18) that projects towards the first end (12) of the convolution; and a bearing section (19) located upstream of the eyelet (17). The coil spring axis (11) and the bending axis (2) are offset in the same direction in relation to the engagement section (14). The longitudinal axis (2) constitutes the bending axis and runs parallel to the coil spring axis (11). The carrier tube (1, 101) is located between an exterior peripheral section of the coil spring section (10) and the fixing section (16), in such a way that it is partially surrounded by the sections. The tine (8) is fixed to the cylindrical carrier tube (1) by a fixing screw (5).
