Claims

The object of the invention is to avoid the named claims without affecting the problem-free processing with a large cutting width

1. Working shaft arrangement of a scissors-required support of the material to be cut axially machine, consisting of on the top or bottom 5 between the circular knives.

Termesserwelle with at intervals corresponding to this is proposed according to the invention that

the desired cutting width fixable the support rings radially divided and embedded over Upper and lower knives, the tangential clamping screws of which are connected to the hubs. To Cutting rings on their outer circumferential surface. Loosening these clamping screws can cause problems guide the material to be cut through and use moderately light support ring parts according to the supported, these areas are supplemented by the desired cutting width changes between the the rubber jackets of steel support rings, circular knives removed or reinserted which are under load frontal adjustment gaps, with the heavy circular knives only axially between the knife hubs lockable on axially adjusted on the shafts and the latter no longer sit on the shafts, which means that 15 must be dismantled.

2. Arrangement according to claim 1, marked support collar over their respective neighboring net by support rings (3 c), which grip with them frontal 20 knife hubs, or by the fact that the tig growing support collar (5) on them knife hubs with a supporting the material to be cut grab the adjacent knife hubs (4). Rubber jacket are covered.

3. Arrangement according to claim 1, characterized in that it is well known to use under knife bushes or indicates that the knife hubs (8) with their cutting rings are radially divisible or slotted from one another feed the material to be cut supporting rubber jacket 25, so that the cumbersome dismantling of the (4 α) are occupied. Knife shaft for the conversion work is avoided.

Here are the cutting sleeves and tion of a winder, consisting of its cutting rings acting as spacer rings on the lower or upper cutter shaft at intervals the end faces flush with one another, so that the corresponding the desired cutting width ascertaining support problem when processing large upper widths and 35 cutting widths that interlock in pairs are not created at all, because each is for Lower knives, the hubs of which are fitted with cutting rings to the cutting work of unused bushing elements Their outer circumferential surfaces take over the continuous support effect. Such a ma-cut material lead and support, with this area machine always requires a lot of expensive and heavy supplemented by the rubber sheaths of steel cutting bushes and cutting rings as spacers, Support rings, leaving the frontal setting 40 while only relatively few of these rings Gap axially between the knife hubs can be used for cutting work.

Furthermore, the previously known Γ cut material can be divided without the 45 radially slotted cutting rings as a spacing path when passing through the distant elements only a gradual change of the cut circular knife pairs between them sags wide, while according to the invention with less or even discards what would lead to disadvantageously uneven manufacturing and operating costs, the stepless width and poor longitudinal edges of the adjustability of the lockable circular knife also cut products. 5 ° is maintained with a large cutting width.
