US Patent:

44271581, Jan 24, 1984

Filed:

Jun 11, 1982

Appl. No.:

6/387645

Inventors:

Peter Conrad - Charlotte NC

Assignee:

Fiber Industries, Inc. - Charlotte NC

International Classification:

B65H 6704
B65H 5426

US Classification:

242 355A

Abstract:

A doffing/donning apparatus is used in combination with a row of winders each of which winds filamentary material upon a tube carried by a rotary spindle of the winder to form a package. The apparatus comprises a carrier mounted for movement generally parallel to and above the row of winders. A column is mounted on said carrier for horizontal movement. A package exchange arm is mounted on said column for up-and-down movement and is alignable with the winder spindle so that the package can be transferred to the package exchange arm. A tube exchange arm is mounted on the column for up-and-down movement and is alignable with the spindle so that a tube on the tube exchange arm can be transferred to the spindle. A shuttle is spaced horizontally from and vertically above the row of winders, and includes a package transfer arm and a tube transfer arm. The package exchange and tube exchange arms are moved along the column to the level of the shuttle.

Appl. No.:

6/752984

Inventors:

Peter Conrad - Charlotte NC

Assignee:

Celanese Corporation - New York NY

International Classification:

B65H 5402
B65H 6704

US Classification:

242 18PW

Abstract:

A winder for filamentary material includes a cutter/aspirator which severs a filament and sucks-in same under negative pressure. The filament travels through a stiff tube while the cutter/aspirator and tube are lowered toward a filament throw-on device as a filled package is being replaced. The stiff tube is connected to a saddle which is mounted on a driven endless belt. The belt travels across an open side of a vertical chamber. A waste duct communicates with the chamber to create a negative pressure therein which is communicated through the belt and to the tube. As the tube is lowered, it is maintained continuously in communication with said chamber to conduct the filament to waste.
