Abstract
The present invention relates to a winding device (1) and a method for winding a frame (7) to produce a fibre material blank (18). For this, a frame (7) is clamped in a clamping device and put into rotation about a rotational axis (5) by a drive (3). According to the invention it is provided that fixing pins (6) are folded down during the passing of a thread (9) to be wound.

Winding device (1) for producing a flat fibre material blank (18) comprising a stationary device (2) with a drive (3) and a clamping device, wherein a frame (7) can be clamped in the clamping device, so that by rotation of the frame (7) a fibre material in the form of a thread (9) or fibre roving is wound on this, characterised in that a rotational axis (5) is arranged centrally to the clamping device, wherein a fixing disc or star-shaped arms on which holders are displaceably mounted, extend from the rotational axis (5), and the holders project from the fixing disc or the arms (4) wherein by displacement of the holders frames (7) having mutually different external geometries can be clamped in the clamping device, and are rotatable through the drive (3), and so that a thread eye (10) movable relative to the frame (7) is provided for feeding a thread (9), wherein when executing the rotational movement (ω) and before the passing of each holder of the thread eye (10), the holder is shiftable relative to the arm or the fixing disc.
Method for producing a fibre material blank (18), wherein this is produced as a flat fibre material blank in a winding device (1) according to the features of at least claim I by winding a thread (9) on a frame (7), characterised by the following steps:
- provision of a frame (7) with individually desired outer geometry,
- clamping of the frame (7) by sliding the holders on the arms (4) or the fixing disc, wherein a distance (a) is formed between the arms (4) or fixing disc and a back (15) of the frame (7),
- attachment of a beginning of the thread (9) to the frame (7) and rotation of the frame (7) about the rotational axis (5),
- relative movement of the thread eye (10) from a front side of the frame (7) to a back side and in turn to the front side, so that in each case a section (11) of the thread (9) covers the particularly hollow interior (12) of the frame (7) on the front side and back side, or
- relative movement of the thread eye (10) such that the fibre roving exiting from the thread eye (10) is wound around an extension on the outer side of the frame (7), so that the sections (11) of the thread (9) only cover the front side or the back side of the hollow interior (12) of the frame (7),
- removal, of the fibre material blank (18) wound on the frame (7).
