Definitions
- a cutting arrangement for cutting paper or sheet webs is provided.
- the present invention relates to a cutting tool set for cutting paper or sheet webs, particularly for cutting off product packings by successive cutting through cross sealed areas of a tubular packing material with enclosed products such as edible ice bodies, comprising a knife with a sharp edge and means for pressing the knife against an anvil for cutting through an intermediate web.
- a cutting tool set for cutting paper or sheet webs, particularly for cutting off product packings by successive cutting through cross sealed areas of a tubular packing material with enclosed products such as edible ice bodies, comprising a knife with a sharp edge and means for pressing the knife against an anvil for cutting through an intermediate web.
- flow packing systems e.g. for packaging of ice lollies
- the products are supplied with mutual spacing to an advanced paper or sheet web, which is currently folded about the products to form a tubular wrapping, this being currently closed by a length sealing and by cross sealing in the areas between the products.
- a cutting of the web is effected through the cross sea ⁇ led areas for successive separation of individual packings.
- this cutting is effected by means o*f a knife and a backing anvil mounted on opposed rotary shafts, between which the sheet web is advanced.
- the knife may have a straight or an undulated cutting edge.
- the knife and/or the the anvil may be supported resiliently in the radial direction.
- the knife should be positioned relative to the anvil with regard being had to the type and dimension of the web to be cut.
- the pres ⁇ sure between the knife and the anvil should be adapted to this positioning and the said web conditions. If the pressure is too weak the knife may not cut the web entirely, e.g.
- the knife and the anvil may be arranged resiliently relative to each other, but still it is difficult to ensure both an efficient cutting and a long li ⁇ fetime of the knife. It is necessary to adjust the positions of the knife and the anvil very precisely for securing a safe cutting operation.
- the possible resilient depressability of the cutting edge will be limited to a range of some 0.05 mm, i.e. a very short movement. For that reason it is also relevant to consider a possible compressability or resiliency of the he ⁇ avier portions as constituted by the shoulder and abutment parts, inasfar as this should be taken into account in con- nection with the magnitude of the required actuation pressure if the tool parts are to be held reasonably small sized.
- the resiliency or yieldability of these faces can be modified, e.g. by a suita- ble material choice or by a formatio of grooves in the surfa ⁇ ces.
- such grooves will contribute to a more well defined deformation, because the grooves, during the cutting operation, will act as channels through which any possible dirt can be forced away.
- the actual force may be adjusted through a suitable choice of the resi ⁇ liency of such a spring system.
- the anvil may be provided with an unbroken surface, wit ⁇ hout any jump along the cutting line. In that case the edge deformation is predominantly defined by the level of the shoulder faces relative to that of thee knife edge.
- the anvil can be made with a pair of shoulder portions, the positions of which in the* cutting line corresponds to the shoulder faces on the knife element.
- This may be advantageous if, for example, the material choice for the elements of the cutting system is conditioned by other production conditions, such that a safe cutting is not neces ⁇ sarily ascertained by a cutting arrangement with a planar ba ⁇ sis.
- the knife edge may be designed as a straight edge or a zig-zag shaped or undulated edge, all accordinging to the desired type of the cutting.
- the knife and the anvil may be pressed together through rotary or translatoric movements or combinations thereof.
- Fig. 1 is a schematic side view of a cutting arrangement
- Figs. 2 and 2a are perspective views of an associated knife with with shouylder faces
- Figs. 3-5 are front views of different embodiments of the shoulder faces on the knives and the corresponding faces on the anvil in the cutting arrangement; and Figs. 6 and 7 are side views of alternative embodiment of a cutting arrangement according to the invention.
- a cutting arrangement comprising a knife 1 and an anvil 2 mounted in a rotary manner on a cutter cylinder 10 and a backing cylinder 20, respectively.
- a mate ⁇ rial web 3 is advanced between the two cylinders 10 and 20.
- this web 3 is tubular and contains ice products. Upstream of the cutting station the web has be ⁇ en subjected to cross sealing operations such that the ice products are present in respective tube cells, which are then cut free by cross cutting, resulting in bag members with one product in each.
- the knife 1 is mounted on the knife cylinder 10 backed by a spring arrangement 8.
- a knife 1 belonging to a system according to the inventi- on is shown in more detail in Figs. 2 and 2a * .
- this knife is provided with shoulder formations 5.
- Each of these has a shoulder face 6 abutting against corresponding abutment faces 9 on the anvil 3, see Figs. 3-5.
- the knife 1 has a cutting edge 4, which may be a zigzag edge as illustrated or a straight edge.
- the shoulder faces 6 may be divided in a number of sub faces by way of grooves 7 provided in the surfaces, whe ⁇ reby these will be easier to deform resiliently by pressure.
- the knife edge 4 may be staggered relative to the shoulder faces, such that these are slightly retracted from the edge 4 as shown in Figs. 3 and 4, while in Fig. 5 the shoulder faces project slightly in front of the edge.
- the distance designated A between the faces 6 and 9 or 9 ' and 9", respectively, is the spacing that occurs when the knife edge in unloaded condition rests on the anvil. If the system except for the knife edge is considered to be totally stiff, then this spacing should be the same or a little less than the distance over which it is possible to pressure deform the knife edge purely resiliently, e.g. 0.05 mm. It should be noticed, however, that the system is not en ⁇ tirely stiff, as this may condition that for a continued building up of pressure once the parts 6 and 9 have been brought together, a certain further movement may occur which can contribute to the deformation of the knife edge. In par ⁇ ticular when the system is laid out for enabling higher cut ⁇ ting pressures it will be relevant to take into account the resiliency not only of the edge area, but also of the remai ⁇ ning tool parts.
- Figs. 6 and 7 show two alternatives to the arrangement according to Fig. 1.
- the knife 1 is guided in a li ⁇ near path with the anvil 2 rotating on a backing cylinder 20.
- this cylinder itself could constitute the anvil if made with sufficiently hard surface.
- both the knife and the anvil are guided in a linear manner; here, the anvil could be stationary and only the knife be movable.
