Machine for the production of corrugated cardboard

The invention relates to a double-sided chiropractic machine of the variable-action type; a typical construction of such a machine is described, for example, in U.S. Patent No. 2 941 575.

In the iuas chine according to the UBA patent mentioned, an optimal construction is achieved in that only a single pressure roller is provided near the rear end of each heated plate. In addition, the heatable plates can be moved downwards away from the corrugated cardboard to be produced and, for this purpose, can be pivoted about their rear index or brought into an upright position. In accordance with the present invention, it has now been found that the overall length of the double-sided laminating machine can be reduced by providing additional pressure rollers to produce more even pressure between the heated platens and the corrugated board. If such additional pressure rollers are provided, however, the advantages of the double-sided working machine with variable heating effect are lost, since the additional iuidrucj; .vvi'.lzen the corrugated pc'j ^ pe both at the top and at the top ^ ren, .. it'llung the i ^j Lr'itl / Orj in Lex-ührurir; .with the i-'intten-bnl. l; (.; ii. hi. r-b'-i

TJm a shortening of the length of the mentioned double-sided to enable working cash machine and still To maintain the advantages of a machine operating with a variable heating effect, the invention now provides one automatic device by which the additional Andru £ ßkwalzen depending on the movement of the heated Plates are controlled when the amount of .touch between the corrugated cardboard and the top of the heated plates is reduced as the plates move away from the corrugated cardboard, causes the automatic control device that the The automatic control device preferably comprises mechanical ones Lever and linkage so that there is a device of simple construction results, which can be produced with low costs and reliable; is working.

the position of the pressure rollers is equipped, wob -., i the Healing device is simple in construction, can be manufactured at low cost, and is reliable.

The invention and advantageous details of the invention are in the following to H;:. nd schematic rejections explained in more detail using an exemplary embodiment.

Ed. 1 shows a machine for double-sided sealing of corrugated cardboard in a side view.

Pig. 2 is an enlarged and foreshortened section along the line 2-2 in i'ig. 1.

i'ig. 3 shows the arrangement of FIG. 2 at B-. aspiration same from line 3-3 in i'ig. 2, the one shown Plate assumes its highest position, at which it gives off a maximum 'amount of heat to the corrugated cardboard.

i'ig. 4 is similar to iig. 3, however, shows the plate in its lowest position, in which it gives off the smallest possible amount of heat to the corrugated cardboard.

In the figures, similar parts are each denoted by the same reference numbers; in l ^r ig. 1 shows a machine designated as 10 for the production of corrugated cardboard laminated on both sides. The machine 10 comprises an endless belt 12 which runs over rollers 14 and 14 ', one of which is drivable. The corrugated cardboard 16 is pulled through the machine 10 with the aid of the belt 12, the corrugated cardboard being brought into contact with the top of a plurality of adjustable heating plates 18, 20, etc.

Since all of these plates are of the same construction, only one plate 18 is described in more detail below. The plate 18 has an upper surface that is in intimate contact can be brought with the corrugated cardboard 16 so that heat is transferred from the plate 18 to the corrugated cardboard 16 in order to gluing a sheet of lamination material with an e. nside
