Abstract
The device for embossing Braille code characters on a movable paper web includes a set of plungers supported for reciprocating movement against a stationary matrix for embossing dots in respective lines; a continuously reciprocating beam is arranged below the lower ends of all plungers and each plunger cooperates with an actuation device such as a solenoid which selectively deviates the lower end of the plunger out of engagement or into engagement with the impact surface of the reciprocating beam.
Claims17
A device for embossing Braille code characters comprising an embossing matrix provided with recesses arranged according to Braille code dot lines, means for moving a web to be embossed past the recesses of said matrix, a set of stamping plungers arranged for a vertical reciprocating movement opposite said recesses in the matrix, means for guiding top ends of respective plungers into the recesses, a beam supported for a continuous reciprocating movement at the lower ends of said plungers, a plurality of actuating members coupled to respective plungers for selectively moving the same out of engagement or into engagement with the continuously reciprocating beam, said reciprocating beam supporting an impact surface cooperating with the lower ends of said plungers, said actuation members being coupled to the lower portions of said plungers for swinging the same in a transverse direction relative to the direction of the vertical reciprocating movement, whereby the lower ends of said plungers are selectively brought into and out of engagement with said impact surface, said beam being provided with guiding and retaining means for said plungers, and lower end portions of said plungers being formed with stepped members engageable with said guiding and retaining means during a return stroke of said beam.
