Abstract
Official abstract text for this publication.
The present invention relates to a method for forming and transferring an unbonded fibrous structure to a carrier, the method comprising the steps of: receiving fibrous material on a shell travelling at a first speed through a receiving zone to form a fibrous patch; transferring the shell from the receiving zone to an application zone; applying the fibrous patch to the carrier travelling at a second speed through the application zone; and controlling the speed of the shell by a motor, the motor comprising a stator and at least one mover; wherein the shell is driven by at least one mover, wherein the mover maintains the shell at the first speed in the receiving zone and the second speed in the application zone, and wherein the mover is mounted on a stationary track.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for forming and transferring an unbonded fibrous structure to a carrier, the method comprising the steps of: receiving fibrous material on a shell travelling at a first speed through a receiving zone to form a fibrous patch; transferring the shell from the receiving zone to an application zone; applying the fibrous patch to the carrier travelling at a second speed through the application zone; and controlling the speed of the shell by a motor, the motor comprising a stator and at least one mover; and wherein the shell is driven by at least one mover, wherein the mover maintains the shell at the first speed in the receiving zone and the second speed in the application zone, and wherein the mover is mounted on a stationary track. 2 . The method of claim 1 , wherein the stator comprises a plurality of stationary electromagnets. 3 . The method of claim 2 , wherein the movers comprise permanent magnets and wherein the variable speed of the movers along the stationary track is controlled by varying the current supplied to the stationary electromagnets. 4 . The method of claim 1 , wherein the stationary track follows a continuous, closed path. 5 . The method of claim 4 , wherein the closed, continuous path is a circular path. 6 . The method of claim 1 , wherein the fibrous material is held against the shell, at least in the receiving zone by vacuum. 7 . The method of claim 1 , wherein a plurality of shells travel at the first speed through the receiving zone and at a second speed through the application zone, and wherein the speed of each shell is independently controlled by at least one mover.
