  • Adjustable compression roller apparatus
    Patent number: 4127066
    Abstract: A pressure-roller apparatus comprising two compression rollers providing a pressure nip therebetween for the introduction of sheets or other thin members to be compressed and fed. The degree of pressure in the nip is variable by means of one or more adjustment roller assemblies comprising adjustment rollers which are substantially shorter in length than said compression rollers and which engage one of said compression rollers at one or more points intermediate its ends to provide an intermediate and balanced pressure adjustment which avoids bowing of said compression roller.

  • Continuous duplicating process
    Patent number: 4121522
    Abstract: A dry duplicating method comprising the steps of pressure-imaging a continuous master web with images capable of exuding liquid ink under the effects of contact pressure such as roller pressure and collecting the imaged master web on a roll for duplicating use. The master web is such that at least one surface is receptive to the pressure-applied images but neither surface is capable of absorbing the liquid ink to any substantial degree. The imaged web is duplicated by continuously bringing it into surface contact with an ink-absorbent copy web while pressure is applied to exude the liquid ink from the master images onto the copy web to form a duplicate copy, after which the web is continuously rolled up on another roller for reuse.
