Embodiment 1

[0074] Embodiment 1: An apparatus for applying a first web in a non-linear pattern to a base web as it advances in a machine direction as it contacts a backup roll, the apparatus comprising: guide rolls; and guide roll translation a system; wherein the guide roller is configured to define a nip with the backup roller, the guide roller translation system is configured to allow movement of the guide roller relative to the backup roller to control the position of the nip, Thereby allowing the first web to be applied to the base web in the non-linear pattern in the machine direction.

Embodiment 2

[0075] Embodiment 2: The apparatus of embodiment 1, wherein the guide roller is configured to move in a transverse direction relative to the backup roller.

Embodiment 3

[0076]Embodiment 3: The apparatus of embodiment 1 or embodiment 2, wherein said guide roller comprises a guide roller axis of rotation, and said backup roller comprises a backup roller axis of rotation, and wherein said guide roller axis of rotation is capable of relative to said The backup roller axis of rotation pivots such that the guide roller axis of rotation defines a lead angle with the backup roller axis of rotation.

Abstract

Apparatus and methods for applying a first web in a non-linear pattern to a base web as it advances in the machine direction in contact with backup rolls are disclosed. The apparatus may include guide rollers and guide roller translation systems. The guide roll may be configured to define a nip with the backup roll. The guide roll translation system may be configured to allow movement of the guide roll relative to the backup roll to control the position of the nip, thereby allowing the first wire to move in the non-linear pattern in the machine direction Applied to the base net.

Description

Background technique [0001] The present invention relates generally to apparatus and methods for applying a first web to a base web, and more particularly to apparatus and methods for adhesively bonding a first web in a non-linear pattern to a moving base web method. [0002] Absorbent articles such as disposable diapers, training pants, adult incontinence articles, etc. often comprise a number of different components bonded together. A typical absorbent article includes a bodyside liner, an outer cover, and an absorbent core disposed between the liner and the outer cover. In addition to the liner, outer cover, and absorbent core, a typical absorbent article also includes a number of discrete components such as fasteners, waist elastics, leg elastics. These discrete components of the article are typically bonded to the bodyside liner and / or outer cover. For example, it is known to adhesively bond leg elastics in a curved pattern to a continuous web of outer cover material o...
