Abstract
A guide encloses a group of traveling filaments arranged in a pattern forming a main longitudinal axis. The guide comprises a carrier movable toward and away from the filament group. A plurality of relatively movable members are mounted on the carrier for movement between open and closed positions. Those members form a through-passage for the filament group in the closed position. An actuating mechanism is operatively connected to the carrier and members for extending the carrier toward the filament group, and closing the members around the filaments to converge the filaments. Thereafter, the carrier is retracted to a position where a longitudinal axis of the through-passage is substantially aligned with the main longitudinal axis formed by the filament group.
Claims6
The combination of a spinneret for forming a group of filaments, and a guide disposed below the spinneret for guiding said group of filaments whereby such group forms a main longitudinal axis, said guide comprising:
- a carrier movable forwardly toward and rearwardly away from a location where the filament group defines a first cross-sectional area,
- a plurality of jaws movably mounted on said carrier for movement between:
- an open position, and
- a closed position in which said jaws close to form a through-passage which defines a second cross-sectional area smaller than said first cross-sectional area of the filament group and
- actuating means operatively connected to said carrier and jaws for:
- displacing said carrier forwardly toward the filament group to a filament-capturing position with said jaws open,
- closing said jaws around the group of filaments to converge all the filaments within said through-passage, with a longitudinal axis of said through-passage being spaced from said main longitudinal axis,
- retracting said carrier and closed jaws rearwardly to an operational position to displace said longitudinal axis of said through-passage to a location substantially aligned with said main axis.
