Abstract:
1. A method of placing a material on a plurality of moving webs, the method comprising the steps of: providing a first web having a transverse width in a first upstream zone such that the first web moves at a first web velocity in the positive x direction; providing a first assembly for diverting the first web from the first upstream zone to a first intermediate zone and for diverting the first web from the first intermediate zone to a first downstream zone; providing a second web having a transverse width in a second upstream zone such that the second web moves at a second web velocity in the positive x direction; providing a second assembly for diverting the second web from the second upstream zone to a second intermediate zone and for diverting the second web from the second intermediate zone to a second downstream zone; periodically overlapping the first assembly and second assembly in an alternating fashion by translating the first assembly and second assembly in a positive x direction in a first plane and a negative x direction in a second plane such that when the first assembly translates in the positive x direction, the first web in the first intermediate zone has a velocity, with respect to the first assembly, which is less than the first web velocity and such that when the second assembly translates in the positive x direction, the second web in the second intermediate zone has a velocity, with respect to the second assembly, which is less than the second web velocity; and alternately applying the material across at least a portion of the transverse width of the first web in the first intermediate zone and across at least a portion of the transverse width of the second web in the second intermediate zone such that the application of the material to the first web and the second web is continuous.
