Abstract
The invention provides textile cores (10) having improved start-up grooves (12). The start-up grooves have a generally V
shaped cross section and in one embodiment, at least one longitudinal portion (14), preferably the leading portion of the groove, has at least one vertically compound angle sidewall (23, 32) with a roughened surface (36) for gripping a yarn line. In another em-bodiment, a start-up groove (161) includes at least one longitudinal portion (167), preferably the trailing portion of the groove, having at least one longitudinally compound sidewall (180, 184) defined in longitudinal cross section by a plurality of alternating, substantially rectangular tongue and notch sections (170, 172) extending along the sidewall. In accordance with other aspects of the invention, improved grooving blades (50, 150) for textile cores are provided and are formed using an electric discharge ma-chining (EDM) process.
