MACHINE FOR TAKING OFF SINGLE STRIPS FROM A FILE OF PAPER STRIPS. I
Specification 0! Letters Patent.
Patented Aug. 26,1913.
Application nl'ed lieoembot 27, 1211. Serial m. eas est.
To all whom it may concern:
Be it known that I, 'HENRYK Konxmwloz, factory manager, a subject of the Czar of Russia, residing at Wolchowskoi Per 4, St. Petersburg, Russia, have invented certain new and useful Improvements in Machines for Taking off Single Strips from Piles of Paper Strips; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to apparatus for taking off single paper strips of sheets from a pile and feeding them to other operative partsin machines in which paper is dealt with in separate sheets, such as printing, ruling or pasting machines.
According to the present invention a piercing separator-is arranged beneath the pile of paper on top of which is placed a suspended hinged pressure bar pressing on the said pile at two places, just above the piercing knife and just above the feeding cam, in such manner that the end exerting pressure above the piercing knife remains constantly on top of the pile and the end pressing above the feeding cam is automatically dropped on the pile every time the feeding cam touches the paper pile from underneath and feeds the lowest sheet or strip forward, and is automatically raised from the pile as soon as the next operative part of the machine takes hold of the forward end of the strip and the rear end thereof is cut through by the piercing knife. This pressure relieving device is of especial importance in allcases where thin or limp paper is dealt with which would otherwise be exposed to the risk of tearing during its removal from the pile.
In the accompanying drawings, Figure 1 is a vertical longitudinal section of the mechanism, Fig. 2 is a similar section with the pressure bar and feeding cam in another position, and Fig. 3 is a vertical cross sec- 0!? an inclined knife 6 (see Figs. 1 a
its own weight, the rod against the fixed stop pin t and the pressure bar a is held suspended above the paper pile b. The lockplate a and the pin t, are carried by the upwardly extending arm a of the rocking lever 1', which is moved up and down by means of the cam 0. On the downward movement of the lever 1', the lockplate it strikes the projection w of the container and is thereby raised, thus releasin the rod is, and the pressure bar 0 is allowed to fall and rest on top of the paper pile. On the upward movement of the lever r, the lockplate a ams the rev 70 and the pressure bar a is raised. This raising and falling of the pressure bar 0 relates only to that end of it wh1ch is over the feeding cam h the other end resting the whole time on the paper pile.
