Abstract
A method and system for automatically changing the flute size in a corrugation process without stopping or slowing the overall corrugation process utilizing a first single-faced web having a first flute size and a second single-faced web having a second flute size. The first single-faced web is conveyed along a track into a double backer forming a first corrugated material. When a flute change sequence is initiated, the single-faced web is cut using a pressurized stream of water such that the single-faced web disengages with the double backer. Generally simultaneously, the second single-faced web is introduced into the double backer using an air jet, wherein a second corrugated material is formed.
Claims20
An apparatus comprising:
- a single backer machine adapted to form a single-faced web by securing a first backing material to a fluted material, wherein the single-faced web includes a leading edge;
- a double backer machine adapted to form a corrugated material by securing a second backing material to the single-faced web;
- an inlet disposed on the double backer for receiving the single-faced web;
- and
- an air table configured to selectively convey the leading edge of the single-faced web into the inlet by way of an air stream.
An apparatus comprising:
- a single backer machine adapted to form a single-faced web by securing a first backing material to a fluted material, wherein the single-faced web includes a leading edge;
- a double backer machine adapted to form a corrugated material by securing a second backing material to the single-faced web;
- and
- a water jet cutting device adapted to selectively expel a pressurized stream of water through the single-faced web to form a cut in the single-faced web.
An apparatus comprising:
- a first device adapted to form a first material;
- a second device adapted to form a second material;
- a third device, wherein the third device selectively receives one of the first material and the second material, and wherein the third device is adapted to form a third material from the one of first material and second material received thereby;
- and
- a means for selectively switching which one of first material and second material is received by the third device.
