Description

1 TITLE A Cutting Roller for Slitting Machines.
2307878 This invention relates to a cutting roller for a slitting machine, primarily for processing wide film webs, and to a method for the manufacture thereof.
For processing webs of plastics material, paper of the like, winding machines are used for dividing the material web io into narrow individual webs and for winding said webs into rolls. In the case of slitting machines for wide film webs, longitudinal cutting devices are conventionally used which comprise individual, transversely adjustable knives and a cutting roller which supports the web as a counter roller and has a plurality of circumferential, annular grooves, which the blades of the knives penetrate during cutting. A known kind of cutting roller, which is formed by a series of grooved bushes fitted over a shaft is disclosed in DE-OS 27 41 908.
In the case of slitting machines for wide film webs (web width exceeding 7 m), the cutting rollers, which are usually made of steel, need to have a large diameter with a correspondingly high weight for reasons relating to stability. The resulting low critical rotational speed restricts the working velocity. Furthermore, the space available for the cutting roller in the slitting machine is limited.
41635.spe It is the object of the invention to provide a cutting roller with a large axial length for processing very wide film webs which have a lowweight and a small diameter.
According to this invention there is provided a cutting roller for slitting machines with a plurality of annular grooves extending circumferentially with planes at right angles to the axis of rotation, by a hollow cylindrical support element made of a fibre compound material, onto the cylindrical surface of which a thin metallic layer is applied into which the grooves are io machined.
According to this invention there is also provided a method for manufacturing a cutting roller in which method a hollow cylindrical support element manufactured from a fibre compound material has a thin layer of a metal applied to the outer cylindrical surface thereof by means of a thermal spraying process, grooves then being machined into the metallic layer.
The invention is further explained and illustrated by means of an embodiment as example and shown in the drawings, wherein:- Figure 1 shows a simplified cross-section, not to scale, through a cutting roller and Figure 2 shows a detail from Figure 1.
In the drawings the cutting roller 1, which extends over the entire working width of the slitting machine, has a diameter 3 of 400 mm to 650 mm and comprises a hollow-cylindrical support element 2 made of a fibre compound material, preferably a carbon fibre resin compound with longitudinally extending fibres. At each end face, a shaftjournal 3 is secured coaxial to the axis of rotation 4, the cutting roller 1 being mounted on said shaft journals 3 in the frame of the slitting machine. The radially measured thickness of the cylinder shell of fibre compound material forming the support element 2 is dimensioned as a function of the roller length, so lo that the required stability is obtained. If the external diameter is about 500 mm, the thickness is about 20 - 30 mm.
A thin metallic layer 5, preferably of aluminium but alternatively of steel, is applied to the outside of the entire cylindrical surface of the support element 2. Annular grooves 6, which extend around the circumference in planes at right angles to the axis of rotation 4, are machined in the layer 5. The thickness of the metallic layer 5 measures less than 5 mm, but more than the groove depth of the grooves 6, so that the base of the grooves 6 is also made of metal. A metallic layer with a thickness of about 0.5 mm preferably remains beneath the grooves 6. The depth of the grooves 6 preferably measures 2 to 3 mm, their axially measured width and the width of the intermediate webs 7 measure about 1 mm.
According to a preferred embodiment, the outer surface of the metallic layer 5 with the grooves 6 and webs 7 is coated 4 with nickel in order to increase the hardness.
The manufacture of the cutting roller 1 is effected in such a manner that the hollow cylindrical support element 2 is firstly manufactured from a fibre compound material. It is preferably made of a carbon fibre resin material with longitudinally extending fibres. A thin layer measuring less than 5 mm of a metal, preferably aluminium, is then applied to the outer cylindrical surface of the support element 2 by a thermal spraying method, for example by flame or plasma spraying.
io The grooves 6 are then formed by cutting or chip-forming machining in the metallic layer 5. After the machining of the grooves 6, the outer surface of the metallic layer 5 is coated with nickel in order to increase hardness by a chemical depositing process without an external current source.
