Apparatus and method for making a corrugated product

摘要

The invention describes a device and method for making corrugated products. The device can be used with any substrate and includes, at least, first and second drive rollers for driving a middle substrate and a single wall corrugated product. In other embodiments the invention includes upper drive rollers, lower drive rollers and middle drive rollers for driving an upper substrate, a lower substrate and a middle substrate. The middle substrate is driven between the upper and lower substrates at a higher velocity to form flutes that are anchored between the upper an lower substrates thereby forming a corrugated product. The invention also provides for customized corrugated products having multiple fluted substrates in various desirable arrangements. Examples of such products include mattress, partition panels, other furniture and construction products.

主权项

1. An apparatus to prepare a corrugated product, comprising:
(a) a first pair of drive rollers to drive a middle substrate, actuated to have a velocity V3; (b) a form guide; wherein the form guide provides an upper surface to guide an upper substrate and a lower surface to guide a lower substrate; (c) a second pair of drive rollers actuated to have a velocity V1; (d) wherein V3 is greater than V1 and the first pair of drive rollers is configured to drive the middle substrate into a space delimited by the form guide such that the middle substrate buckles and alternately contacts the upper and lower substrates; (e) a bonding device positioned about the upper surface and the lower surface of the form guide, wherein the bonding device attaches the middle substrate to the upper and lower substrates; wherein a corrugated product is prepared.
