The invention relates to a method for severing "metal strip or a metal sheet transversely to the direction of advance" into strips. ;. . ,; '■ · ■■ "" "

Strip-shaped metal sheets, e.g. eats apparatus and equipment construction "Can be used for economic reasons in general not "rolled directly from a slab" but must be done by severing a meta11 strip that has been rolled out over a large area or by cutting metal strips into, oils from metal strips are cut off ".

According to a known method, the strips are by means of of an upper and lower teaser along the dividing line from the metal strip or the i.Ietalltafel sheared off (Dubbels Taschenbuch für Liaschinenbau, 1965, 12./Vuf 1,., Volume II ,, p. 733 "). The so. Separated strips, however, experience warping and are saber-like deformed the strips are straightened again in a special device must, but the strips are only poorly assessed - '/ eise geliing.'t ;, νν; Ί & subsequent dimensioning and processing makes necessary.

It is also known that I veneer rolled to straighten the edges. tapes or I.ietrill plates, cutting tools must be used (d. P.S. 1. 022 079). Jedoc'h are cutting tools never been mentioned in connection with the severing of narrow strips from thin metal binders or ketalltafe'ln.

The invention is based on the task of creating any narrow strips to be separated from particularly thin metal strips or metal plates, without the stripes being discarded or deformed like a saber and are lengthened and ridges are preserved.

This object is achieved according to the invention in that the or 'the metal strip or metal plate of with at least one cutting tool at right angles to the feed direction at least one groove, the depth of which is at least half the thickness of the metal strip or tile tall ta field is, and that then the Hestmaterial is broken by pivoting movements of the strip to be separated.

Several cutting tools can be used to create a groove with. be connected in series with increasing penetration depth. The service life is thereby increased in an advantageous manner.

As cutting tools, pens in particular can be used with hard and pyramid-shaped ground material Points as well as planing or lathe chisels, also around their longitudinal axis rotating pinger milling cutters and mounted points or in the same or grinding wheels rotating in the opposite direction to their feed movement, Circular saws and milling cutters are used.

In order to be able to break through the residual material left under an introduced groove with as little swiveling movement of the strips to be separated as possible, the groove must be made deep. However, it must not be inserted so deep that - the material is on the metal strip opposite the grooves - or on the first side of the metal sheet. under -the pressure of the cutting tool - is pushed out of the smooth metal strip or metal sheet surface and the TJunterlageoberflache could be damaged · over ^90;; ί of metallic tape or metal panel thickness -..

The formation of an undesired burr on the surface of the strip could prove to be an additional part of the cutting through of the metal strip or the metal parts in one operation inserted .dille is bent in. / ".

After making the "groove, the spa na" :: lifts "tool its return, whereby it is raised or pivoted slightly away or can run back through the groove with the same height setting as when the Hille was introduced. Jodann will the stripes are marked by jerking movements. of course this breaking off of the strip is also before the Return of the machining, Verkzeunes possible. Finally receives the He tallband or the metal sheet for introducing the next Hille in the direction of the cutting tool Feed, which corresponds to the width of the strip then to be separated. ~ 'It can therefore' depending on the advance of the first metal belt or strips of different widths can be separated from the metal sheet.
