The invention relates to a slitter mission is to continuously "= lent funded, For Example directly from the extruder coming plastic pipes _$ as they are needed for drainage purposes ^ and has the task" - a fully automatic operation of such Sehlitzvorrichtung- with high performance and good adaptability to the most diverse requirements, such as ZoBo "Eohrdiameterj slot length and distribution of the slots over the circumference," to enable.

not only pipes with the usual cross-section narrow, like. z <, B _ö circular, OTaIe ₈ Reehteck-Rohr «© ,, but also. Special shapes with cross-sectional zykloidalem tu like "means one and the same device can be provided with slots _o

For this purpose "there is the device according to the invention basically aas a plurality in one cutting head - ver = · '

actuating adjusting device ο. In this way there is the possibility of _creating a fully automatic slitting device, which with high accuracy and uniformity. Starting from the endless tube, slots of, for example, 0.4 mm wide and adjustable length into which 'continuously from.

Estruder is allowed to cut incoming pipe. Depending on the type and diameter of the pipe, 2 - 24 slots can be made on the circumference of the pipe. it can be adjusted between, for example, 4 and 40 cuts per minute. ”In addition, the device according to the invention allows a high working speed since the RoJar throughput speed is approximately between 0 _? .5 and 5 ß / min are feann ₀ -

According to a preferred embodiment, there are individual cutting devices each from a motor with saw

Since drainage pipes are generally laid in pieces of rope of limited length, it is advantageous if the pre- . ^? The guidance is supplemented by the fact that at a distance behind the Schiitzmaschisie an automatically-'to-be-operated ear-saw for
