Abstract:
A method for labeling for identification by visually impaired persons an article having an arbitrary peripheral surface shape comprising the steps of:unwinding a continuous web of sheet of material to expose a particular segment of said sheet of material for use as a label on said article; directly depositing a viscous liquid on said sheet segment as a tactilely distinguishable marking comprising a plurality of raised substantially round dots, for identifying by touch said article to said visually impaired persons, said tactilely distinguishable marking being formed on said sheet segment without additional deformation of said deposited viscous liquid after application; cutting said sheet segment with said deposited tactilely distinguishable marking from said web; and applying adhesive to attach said sheet segment in incremental portions to said article by depositing adhesive as a plurality of dots spaced either along the sheet segment or around the periphery of said article at the location where the sheet segment is to be applied before the sheet segment is applied such that a first dot of adhesive is applied near the leading end of the sheet segment or the location on the article where the leading end will be attached and other of said plurality of dots are applied at predetermined distances from the previously applied dot so that as the sheet segment is applied to said article, incremental portions of the sheet segment are held firmly on said article as each incremental portion of said sheet segment is contacted to successive ones of said adhesive dots as said sheet segment comes off of a vacuum drum, and it is prevented from relaxing significantly by said sequential adhesion to said dots; said predetermined distance between said dots being selected to provide adhesion of the portion of said sheet segment between the currently applied dot and the previously applied dot.
