Abstract

This apparatus abrades consecutive or repetitive numbers at uniformly spaced locations along a continuously moving web that can later be severed into discrete documents. As in A, two rotary numbering units 1 are oppositely inset in die drum 2 that is driven counterclockwise by shaft 3. Units 1 have cam followers 4 that ride continuously in common cam track 5. Cam 6 includes a shaft encircling ring 7 that is connected to extension 8 pivotally supported on pin 9. Cam 6 can be rocked into selective contact with on and off stops 10 and 11. When on cam 6, through the followers, indexes units 1 through successive numbers. When off, cam 6 is ineffective to cause indexing and thus conditions units 1 repetitively to provide the same number.

Web Abrading Apparatus

This apparatus abrades consecutive or repetitive numbers at uniformly spaced locations along a continuously moving web that can later be severed into discrete documents. As in A, two rotary numbering units 1 are oppositely inset in die drum 2 that is driven counterclockwise by shaft 3. Units 1 have cam followers 4 that ride continuously in common cam track 5. Cam 6 includes a shaft encircling ring 7 that is connected to extension 8 pivotally supported on pin 9. Cam 6 can be rocked into selective contact with on and off stops 10 and 11. When on cam 6, through the followers, indexes units 1 through successive numbers. When off, cam 6 is ineffective to cause indexing and thus conditions units 1 repetitively to provide the same number. Web 12 is advanced around drum 2 past rough and finish abrading wheels 13 and 14, respectively, that rotate in the directions indicated. These wheels are set to abrade web 12 to a preselected depth only if and when indicia on units 1 are substantially on the line of centers of 2 and 13 or 14.

Thus as drum 2 completes one revolution, web 12 is abraded successively in two locations, one shown at 15, with the depth of abrade varying as desired either at each location or at each digit position at each respective location or both. Thus, if web 12 is a laminate of different colored layers, the number can be in a color contrasting with the unabraded exterior, or the digit positions of the number can be abraded to differ...
