Abstract
An apparatus is disclosed for the cleaning of solubly marked laminated sheets. A laminated sheet is fed over a cleaning surface along which are disposed a plurality of solvent-carrying wipers. The solvent-carrying wipers will wipe the markings from the sheet and the sheet feeder will then deposit the wiped sheet at the other end of the apparatus. Drying means could wipe excess solvent from the sheet following its passage over the wipers. The device will be of particular assistance in the gaming industry, where reusable gaming cards might be substituted for disposable paper cards currently employed for substantial economic savings.
Claims13
An apparatus for use in the cleaning of solubly marked laminated sheets by a solvent, each of said sheets having at least one solvent-impermeable face carrying soluble markings thereon, said apparatus comprising:
- a cleaning surface, said cleaning surface having an intake end and an output end between which is defined a cleaning path;
- a continuous sheet feeding belt which moves a solubly marked laminated sheet over the cleaning surface along the cleaning path from the intake end, with the solubly marked face of the sheet facing the cleaning surface, and deposits said sheet at the output end;
- a solvent source containing solvent;
- at least one sheet wiper disposed on the cleaning surface along the cleaning path, the sheet wiper having a wiping surface facing upwards from the cleaning surface which will contact the solubly marked face of a sheet as it is fed over the cleaning surface;
- the solvent source in communication with the sheet wipers so that solvent is communicated from the solvent source to the wiping surfaces.
