Abstract
A device for rolling up onto a core a stencil or ink screen being removed from a duplicator, in which a pair of rotatable core holding members is located adjacent the or a duplicator cylinder and at least one of the members is driveable from the cylinder by means of a drive wheel carried on a pivotable lever.
Claims15
A device for the use with a stencil duplicator having a rotary cylinder about which is wrapped a stencil or ink screen, said device serving the purpose of receiving the stencil or ink screen as it is removed from the rotary cylinder, comprising:
- a. a frame;
- b. a pair of core holding members freely rotatably mounted on said frame and axially aligned for releasably holding a core therebetween adjacent to and parallel with the rotary cylinder of a stencil duplicator;
- c. lever means mounted adjacent at least one of said core holding members to be pivoted toward and away from the rotary cylinder of a stencil duplicator;
- d. a drive wheel freely rotatably carried by said lever means and being drivingly connected with said one core holding member whereby rotation of said drive wheel produces rotation of said core holding member;
- e. mounting means on said frame mounting said lever means for pivotal movement between a first position whereat the drive wheel carried by said lever means is in rolling contact with an adjacently located rotary cylinder of a stencil duplicator and is driven thereby whereupon a stencil or ink screen carried on the rotary cylinder would be removed and taken up on a core releasably held by said core holding members after the stencil or ink screen has been started on the core and a second position whereat the drive wheel would be out of rolling contact with adjacently located rotary cylinder;
- and
- f. pivoting means for pivoting said lever means between said first and second positions.
