A flat cable winding device includes: a rotation ring positioning a plurality of rollers at an inner circumferential side of the rotation ring, rotating coaxially with a shaft portion formed in a case, and including a circumferential wall portion on which a flat cable wound from outside of the case is wound. The circumferential wall portion includes a notched portion through which the flat cable is routed between an outer circumference side and an inner circumference side of the circumferential wall portion and held. At least one of the plurality of rollers is an inverting roller winding the flat cable wound on the shaft portion and inverting the flat cable toward the notched portion as a rotation table rotates with the shaft portion as a central axis.

Provided is a method for manufacturing a combined yarn bundle including the steps of bringing the two or more carbon fiber precursor yarns which travel approximately parallel to one another into contact with a first roller at a wrap angle of 20 or more. Then, the two or more carbon fiber precursor yarns are split into two and brought into contact with a pair of second rollers, so that the carbon fiber precursor yarns are rotated approximately 90 between the first roller and the pair of second rollers. Next, the carbon fiber precursor yarns delivered from one second roller are brought into contact with a third front roller and a third rear roller, and the carbon fiber precursor yarns delivered from the other second roller are brought into contact with the third rear roller without bringing them into contact with the third front roller, so that these carbon fiber precursor yarns are combined on the third rear roller. Thereafter, the carbon fiber precursor yarns delivered from the third rear roller are brought into contact with a fourth roller to obtain a combined yarn bundle. A ratio of a distance L between axes of the first roller and of the pair of second rollers to a yarn width W of the carbon fiber precursor yarn on the first roller, L/W, is 18 or more and a tension of the combined yarn bundle after delivered from the fourth roller is 0.11 cN/dtex or more.

The invention relates to a cable-processing system comprising: a cable-processing machine (90), especially for automatically processing cable ends of long and/or heavy, relatively flexurally rigid pre-cut cables (80) in at least one cable-processing station (70a, 70b) of the cable-processing machine (90); and a cable transport device (10). The cable transport device (10) is designed with: a cable conveying device (320a, 320b) for transporting at least one of the cable ends (81) of the cable (80) into the at least one cable-processing station (70a, 70b); and a suspension transport device (50) which is designed to transport a cable offcut (80c, 80c1, 80c2) of the cable (80). This cable offcut (80c, 80c1, 80c2) is transported in a suspended manner, for example as a suspended cable wrap (80c). According to the invention, the suspension transport device (50) has at least one guide (51a, 51b, 51c, 51d) and a plurality of suspension transport units (53). These suspension transport units (53) can be displaced in the guide (51a, 51b, 51c, 51d) and are designed as suspensions for the cable offcut (80c, 80c1, 80c2). The suspension transport units (53) are designed in such a way that a cable offcut (80c, 80c1, 80c2) suspended therefrom can be rotated about a vertical axis with or on the suspension transport unit (53).
