Abstract: A process and apparatus for producing BCF yarns, in which a plurality of strand-like filaments are extruded, cooled, and combined into several yarns. The filaments are extruded in the form of a downwardly advancing annular filament sheet, and the filaments in the sheet are cooled by directing a cool air flow radially through the annular sheet. The sheet is divided into segments and the filaments of each segment are gathered to form a multifilament yarn, and each yarn can then be drawn and bulked, and finally wound into a package.

Abstract: A bicycle power train for bicycles, the bicycle power train including a driving sprocket set and a driven sprocket set. A chain connects the driving sprocket set and the driven sprocket set to one another. The chain transfers torque from a sprocket of the driving sprocket set to a sprocket of the driven sprocket set. The torque is transferred to the chain from the driving sprocket via drive teeth disposed on the driving sprocket. The drive teeth each include a drive flank that engages a corresponding link roller of the chain. Each drive flank has a bevel formed thereon, the bevel being shaped to compensate for the lengthening of the chain with wear. The bevel is configured to maximize the number of drive teeth that can simultaneously engage the chain and participate in the transfer of torque over the life of the chain.
