Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 116 words
A machine for paying out lengths of microfilm to be applied to transparent sheets, said microfilm having narrow strips of pressure-sensitive adhesive material adhering to and extending only along the edges of said microfilm and protective tapes on said narrow strips, said machine comprising a support on the machine for a reel of microfilm, a takeup reel on the machine to receive and wind up said protective tapes as they are removed from the film leaving said narrow strips exposed, means to guide the microfilm, driving means for causing rotation of said takeup reel to pull said tapes from said film and to simultaneously advance the microfilm from its reel and along the film guide means.
Claim 2
Dependent Claim 116 words
A machine for paying out lengths of microfilm to be applied to transparent sheets, said microfilm having narrow strips of pressure-sensitive adhesive material adhering to and extending only along the edges of said microfilm and protective tapes on said narrow strips, said machine comprising a support on the machine for a reel of microfilm, a takeup reel on the machine to receive and wind up said protective tapes as they are removed from the film leaving said narrow strips exposed, means to guide the microfilm, driving means for causing rotation of said takeup reel to pull said tapes from said film and to simultaneously advance the microfilm from its reel and along the film guide means.
Claim 3
Dependent Claim 20 words
A machine as claimed in claim 1 having means to guide said tapes from said microfilm to said takeup reel.
Claim 4
Dependent Claim 30 words
A machine as claimed in claim 1 having movable means to support a transparent sheet in position underlying the guided microfilm for application of the film to the transparent sheet.
Claim 5
Dependent Claim 28 words
A machine as claimed in claim 1 having power-driven means to cause rotation of said takeup reel, and control means to start and stop over said power-driven means.
Claim 6
Dependent Claim 35 words
A machine as claimed in claim 3 wherein the transparent sheet support means is slidable laterally with respect to the lengths of microfilm to position said sheet supporting means at different points under said microfilm.
Claim 7
Dependent Claim 58 words
A machine for removing protective tapes from adhesive strips along the edges of one surface of microfilm and for paying out lengths of film with exposed adhesive strips comprising a support for a reel of film, a power-driven takeup reel for receiving and winding up removed protective tapes, and means for guiding the paid out lengths of film.
Claim 8
Dependent Claim 58 words
A machine for removing protective tapes from adhesive strips along the edges of one surface of microfilm and for paying out lengths of film with exposed adhesive strips comprising a support for a reel of film, a power-driven takeup reel for receiving and winding up removed protective tapes, and means for guiding the paid out lengths of film.
Claim 9
Dependent Claim 62 words
A machine for dispensing microFilm having pressure-sensitive adhesive areas on one surface thereof and for removing protective tapes from the adhesive areas to expose the adhesive, said machine comprising a support for a of microfilm, a controlled power-driven takeup reel for pulling said protective tapes from said microfilm and for winding up the removed protective tapes, thereby causing the microfilm to advance.
Claim 10
Dependent Claim 62 words
A machine for dispensing microFilm having pressure-sensitive adhesive areas on one surface thereof and for removing protective tapes from the adhesive areas to expose the adhesive, said machine comprising a support for a of microfilm, a controlled power-driven takeup reel for pulling said protective tapes from said microfilm and for winding up the removed protective tapes, thereby causing the microfilm to advance.
Claim 11
Dependent Claim 153 words
A machine for mounting lengths of microfilm on transparent cards, said microfilm being reeled on a reel and having been previously provided with pressure-sensitive adhesive strips on the edges of one surface of the film, said adhesive strips being covered by protective tapes, said machine comprising a support for said reel, a power-driven takeup reel for receiving and winding up said protective tapes, control means to start and stop said takeup reel, tape guide means to direct said protective tapes from said microfilm to said takeup reel, said protective tapes on being stripped from said microfilm causing the microfilm to pay off its reel and to advance, guide means for the advancing microfilm, support means for a transparent card, said transparent card support means being movable laterally with respect to the microfilm guide means whereby advanced lengths of microfilm having exposed adhesive strips may be positioned to overlie transparent cards for mounting thereon.
Claim 12
Dependent Claim 153 words
A machine for mounting lengths of microfilm on transparent cards, said microfilm being reeled on a reel and having been previously provided with pressure-sensitive adhesive strips on the edges of one surface of the film, said adhesive strips being covered by protective tapes, said machine comprising a support for said reel, a power-driven takeup reel for receiving and winding up said protective tapes, control means to start and stop said takeup reel, tape guide means to direct said protective tapes from said microfilm to said takeup reel, said protective tapes on being stripped from said microfilm causing the microfilm to pay off its reel and to advance, guide means for the advancing microfilm, support means for a transparent card, said transparent card support means being movable laterally with respect to the microfilm guide means whereby advanced lengths of microfilm having exposed adhesive strips may be positioned to overlie transparent cards for mounting thereon.
