Abstract

An apparatus and method for conveying absorbent articles may utilize a conveyor including a vacuum source in fluid connection with a deck. The deck may include a channel. The conveyor may also include a belt including a first surface, an opposing second surface, and an aperture. The second surface of the belt may be in facing relationship with the deck such that the aperture is aligned with the channel. A first row of angled teeth and a second row of straight teeth may be connected with the second surface of the belt. The first row of angled teeth and the second row of straight teeth mesh with a first gear member and a second gear member, respectively. The first and second gear members may be attached to an axle member such that the first gear member and the second gear member rotate with the axle member advancing the belt.

First claim

What is claimed is:

1. A method for conveying absorbent articles, the method comprising the steps of:
providing a conveyor comprising a deck and a belt, the deck including a channel, and the belt including a first surface, a second surface opposite the first surface, and a row of apertures, wherein the second surface is in a facing relationship with the deck;
drawing air through the channel with a vacuum source;
placing an absorbent article on the first surface of the belt;
meshing angled teeth of a first gear member with a first row of angled teeth connected with the second surface of the belt, and meshing straight teeth of a second gear member with a second row of straight teeth connected with the second surface of the belt, wherein the first gear member and the second gear member are connected with an axle member;
advancing the belt in a machine direction;
aligning the row of apertures with the channel by moving the belt in a cross direction; and
holding the absorbent article onto the belt by drawing air through the row of apertures;
wherein the method comprises the further step of moving the second row of straight teeth in the cross direction relative to the straight teeth of the second gear member.

2. The method of conveying absorbent articles of claim 1 , further comprising the step of guiding the belt in the machine direction by supporting the second surface of the belt with a shaft.

3. The method of conveying absorbent articles of claim 1 , wherein the axle member further comprises a roller configured to support the second surface of the belt as the belt advances in the machine direction.

4. The method of conveying absorbent articles of claim 3 , wherein the first gear member and the second gear member are removably attached to the roller.
