Patent ID: 8342834

Claim:
An apparatus for spinning and crimping a synthetic multifilament yarn, comprising a spin unit for spinning a filament bundle, a crimping device for compressing the filament bundle to form a yarn plug, a moveable cooling groove for receiving and advancing the yarn plug while being cooled, a takeup device for disentangling the yarn plug after cooling to form a crimped yarn and then winding the crimped yarn into a package, wherein the width (B) of the cooling groove is dimensioned so that the complete yarn plug can be advanced into the groove in meander form in a plurality of superposed layers, and a drive for driving the cooling groove with a circumferential speed that is slower than the advancing speed of the yarn plug, wherein a spacing (A) is determined between the outlet of the crimping device and the cooling groove, with the width (B) of the cooling groove being at least twice as large as the diameter (D) of the yarn plug.
