Problems solved by technology

[0021] Thus, although the use of heat and high pressure shortens the time required to form a bond between the corrugated sheet and the liner, and thus allows for high throughput, it introduces a number of engineering problems: significantly increasing the cost of the machine and processing time. operating cost
This increases the cost of manufacturing the corrugator

Embodiment Construction

[0132] figure 1 It is shown how the invention can be used in a corrugator and a general description of its operation is given below. Figure 2 to Figure 7 Specific embodiments of rolls and roll parts according to the invention are shown.

[0133] The part of the machine used to form single face corrugated board generally consists of figure 1 Arrow 1 in the schematic side view shown in .

[0134] The first corrugating roll 2 has teeth 2 ′ arranged around the periphery of the first corrugating roll 2 , the teeth 2 ′ extending transversely across the width of the first corrugating roll 2 .

[0135] The second corrugating roll 3 has teeth 3' around its periphery. The diameter of the second corrugating roll 3 is sufficiently larger than the diameter of the first corrugating roll 2 .

[0136] The corrugating rolls 2 and 3 are arranged such that the teeth 2 ′ of the first corrugating roll 2 and the teeth 3 ′ of the second corrugating roll 3 intermesh in the region indicated by ar...

Abstract

The present invention relates to a corrugating roller configured with at least two opposing sides, and a corrugated contact surface about an outer face of the roller, the roller characterized in that the roller includes a passageway from one opposing side to another, the passageway configured to allow fluid flow from the contact surface of the roller to at least one side of the roller, according to a further aspect of the invention the corrugated outer surface of the roller is effectively formed by a plurality of discs located about a common axis and each separated from one another by a radial space.

Description

technical field [0001] This invention relates to improvements in corrugating rolls. The invention has particular application in corrugating cardboard or paperboard. Background technique [0002] Single face corrugated paperboard is well known and widely used in industry, especially in packaging as protective dunnage and wrapping material. It is also used as an essential component in the manufacture of many structural objects such as boxes, panels, pallets, etc. [0003] Multiple single-facer corrugated boards can be bonded together to form multi-layer corrugated boards of various thicknesses and strengths. One reason for the widespread use of this paperboard is its relatively light weight, stiffness and strength. [0004] Single-facer corrugated board is made by bonding a corrugated sheet, usually Kraft, to a liner sheet. The liner sheet is also typically kraft paper, although other materials can be used. [0005] In typical conventional machines for the production of s...
