Abstract

PURPOSE: To draft a sliver at a high draft ratio without unevenness in the ended part, by passing the sliver through specific apparatuses before feeding to drafting apparatuses of a high draft finisher.
CONSTITUTION: A sliver taken out of a can is fed to predrafting apparatuses 32W34 containing pins of a porcupine roller 31 and drafted at a draft ratio of about 1.5 by the porcupine roller 31. The sliver is then fed to drafting apparatuses 34W36 of a high draft finisher and drafted at a high draft ratio. The passage of the sliver through the predrafting apparatuses 32W34 opens fibers in the ended part of the sliver to shift the orientation thereof and eliminates the uneveness of the ended part of the sliver. The ended part of the sliver becomes a complete normal sliver, and the tail ending is possible.
