Abstract
A de-labeler made with easily available structural elements which cooperate to remove a normally non-removable label from a labeled surface of a casing for magnetic media, film, and the like, without using a solvent of any kind. The labeled surface is heated just enough to cause desired viscous deformation of a thin layer of adhesive, or a sufficient decrease of viscosity to loosen the label and enable it to be manually removed, preferably by adhesive failure of the thin adhesive layer. A typical pressure sensitive adhesive ('PSA') is heated to a temperature in the range from 32.degree. C.-65.degree. C. for an interval of time from 5 to 30 seconds, in inverse relationship to the temperature at which the labeled surface is heated. The label is manually peeled away from the surface with a force in the range from 0.5 lb-force to about 10 lb-force, without distorting or otherwise damaging either the casing or the magnetic recording medium encased therein. A de-labeler has a housing with a receptacle adapted to hold the diskette between opposed first and second heater boxes, one larger than the other, mounted spaced-apart, preferably so as to heat only the labeled area; (c) control elements including (i) a timer element to provide a predetermined duration of current of requisite amperage and continuous voltage to at least said first heater box, (ii) a starting switch, and (iii) a signal recognizable by human senses, said control elements being connected to at least said first heater box means.
