Problems solved by technology

Another disadvantage of the invention in PT101980 is the step of perforating the paper before forming the corrugated board, which thus weakens the tensile strength of the paper and thus negatively affects the speed at which the corrugated board can be produced

example 1

[0118] In this example, a paper sheet in the form of double-faced cardboard is conveyed at a speed of 2 m / s. The lasers 7008 fired at a rate of 500 times per second all simultaneously to give longitudinally and laterally aligned perforations with a size of approximately 0.5 square millimeters at a 4 mm pitch.

[0119] Figure 9-11 The ACP is shown in the form of a spiked roller device generally indicated by arrow 1100 . The ACP 1100 has a spike roller 1101 and a backup roller 1102 . The spike roller has a band 1103 of a plurality of radially protruding spikes 1104 . The back-up roll has a series of collars 1105 separated by gaps 1106 accommodating spikes that have penetrated a paper sheet (not shown) passing between the spike roll 1101 and the back-up roll 1102 .

[0120] refer to Figure 12 , shows a machine 100 for making single face paperboard for use in foldable paperboard IBCs as part of a continuous process.

[0121] The machine 100 has a Corcel™ cold process corrug...

Abstract

A machine for creating perforated corrugated board wherein the machine includes : a) at least one apparatus configured to perforate (hereafter referred to as an "ACP") corrugated board after a corrugated board exits the corrugator as part of a continuous process, so that the perforations are spread over at least a portion of the corrugated board.

Description

technical field [0001] The present invention relates to improvements in and relating to corrugated board and its manufacture. Background technique [0002] Corrugated board has many different uses ranging from producing boxes in the packaging industry to advertising and forming point-of-sale displays. [0003] In particular, the use of corrugated board to produce boxes for transporting items such as produce is well known. This application of the invention has particular utility. [0004] Typically, when agricultural products are shipped, breathable packaging is required to extend the shelf life of the agricultural products. To this end, corrugated board produce boxes typically require one or more clearly visible holes or slits in the box walls - to allow airflow to surround the produce therein. For example, a traditional banana box or apple box usually has two or more holes on the box wall, and these holes are usually about 2-5 cm or larger in length / height. However, giv...
