Re .; Additional patent to patent application No. W * f2 775 Ic "^ ^" (W.38 · 51o / 38a ()

In the main patent application, a sawing device for carrying out the method shown has been described, the type of further conveying of the by longitudinal division; resulting partial ^{strips'3o »3 1} iind 32 is of importance _o

The feed of these workpiece strips after the performed Longitudinal division can not only be done by a conveyor belt running underneath, but 'it' Driven, smooth transport rollers with close pitch can also be used to achieve the same effect

With both conveying methods there is a certain risk that when processing plate packets, the upper plate strips will become loyal to the neighbors due to the friction or due to slipping or slipping. Shifting the braking forces in relation to the lower strips o An exactly edge-flush layer of filier layers of a panel package, however, is a prerequisite for a snug cut with tight dimensional tolerances ₀

So it is desirable to have the flush edge location of the packages both lengthways and. also in the transverse direction during the entire dividing process on a plate pack to ensure that Lenc

The orientation of the portion of strip 3 ° »3/1 and 32 transverse to the direction of advance may be, for _o B are ₀ ensured by the fact that the strips after passing dor longitudinal sawing were pushed chtliineai means of laterally attacking Schubstoßel against an opposite Ausri", the alignment on the end Rare can be achieved according to the invention by a feeding and clamping device, which becomes effective again shortly before each transverse section (i.e. inacit the clipping of the partial strips 'Jo _t -' Ji and 32 against the stop stops) and thus the kantexibüxidige position of the plate each time the package stripes are re-established on the crossbars ₀

By interposing a slip clutch or by using a so-called standstill motor in the drive of the post-sowing device, it can be ensured that the drive device is not overloaded even if it is switched off late _{or the like}

The former of drive also allows the further anticipation of a supply device in the event that an adjacent supply device has already reached the clamping state, while the strips lying next to it still in the flow velocity in the direction of the associated stop befin.det _0th
