Abstract:
A cigarette packaging apparatus comprising:a folding station configured to at least partially wrap a label about a pre-arranged bundle of cigarettes;means for repetitively dispensing labels along a pathway leading to said folding station;a first signal generator arranged to generate a signal indicative of a speed of the label along said pathway;a second signal generator adjacent a print location along the aforementioned pathway configured to generate a signal indicative of presence of the label as it passes adjacent said printing location;a first controller which controls said dispensing of said labels and folding operations performed by said folding station;a fluid jet printer head adjacent the print location and a second controller which is in communication with said first controller and which operates said printer head responsive to signals generated by said first and second signal generators so as to controllably apply printed indicia upon a pre-selected portion of said label as it passes said print location; andan arrangement providing a contact-free path portion along which said pre-selected indicia-bearing portion traverses as said label is progressed from said print location to the folding station so that said label arrives at said folding station in an unsmeared condition;wherein said means for repetitively dispensing labels comprises a label-feed roller assembly, said label-feed roller assembly directing said packaging material along said path across said print location, said label-feed roller assembly defines said contact-free path portion downstream of said print location wherealong said applied indicia is maintained in a spaced relation from opposing portions of said label-feed roller assembly;wherein said label-feed roller assembly includes a fixed housing portion, said fixed housing portion including a grooved guide rail along said contact-free path portion; andwherein said label-feed roller assembly includes a grooved roller at a location along said guide rail.
