Abstract
A tape tab cutting and applying mechanism in which a rotating orbiting tape head picks up a tape tab at one station and transports it to an applying station for applying tape tabs at spaced intervals on a moving web or line of successive objects. The tape tab is essentially perpendicular to the path of the tape head at the pick-up station and parallel to the web or article at the applying station.
Claims11
An apparatus for applying tape tabs at spaced intervals on the surface of a continuously moving web as the web passes through a tape tab applying station, comprising:
- a. an orbitable, rotatable, tape tab handling member having a generally flat tape tab carrying surface;
- b. grip means associated with the carrying surface for holding the tape tab in contact with said carrying surface;
- c. orbit means operatively associated with said member for moving said member through an orbital path which approximates the plane and the velocity of the web at the applying station;
- and
- d. orienting means operatively associated with said member for orienting said carrying surface parallel the surface of the web as said member approaches and moves through the applying station, whereby said tape tab and the surface of the web in the applying station are substantially parallel when they approximate and contact and wherein said orienting means comprises a planetary gear and a stationary sun gear, the planetary gear being attached to said member, and the planetary gear being operatively associated with the sun gear.
An apparatus for cutting tape tabs from a bulk strip of pressure sensitive tape and applying the tape tabs at spaced intervals on a continuously moving web as the web passes through a tape tab applying station, said apparatus comprising:
- a. a rotatable arm;
- b. drive means connected to said arm for rotating said arm;
- c. a tape tab handling member being rotatably mounted on the arm radially outwardly from the center of rotation of the arm;
- d. said tape handling member having a tape tab carrying surface and a knife edge parallel to and adjacent the carrying surface;
- e. grip means for holding a tape tab in contact with the carrying surface;
- f. a sun gear being concentric with the arm;
- g. an intermediate gear being engaged with the sun gear;
- h. a planetary gear attached to said member and engaged with the intermediate gear;
- i. said gears being engaged so that the carrying surface is parallel to the web at the applying station;
- j. the center of rotation of said arm being a distance from the tape applying station so that the path of the carrying surface during rotation of the arm tangentially contacts the web at the applying station;
- k. an anvil being outside and adjacent the path of the knife edge, whereby the knife edge and anvil cooperate to sever tape tabs from the bulk strip of tape laying across the anvil when the knife edge passes the anvil during rotation of the arm;
- l. tape release means for breaking any bond between a severed end of the bulk strip of tape and the anvil which may be formed when a tape tab is severed from the bulk strip;
- m. a lubrication roll having a deformable, resilient peripheral surface containing a lubricant, said surface being tangential to the path of the knife edge so that the knife edge contacts the lubrication roll surface after it cooperates with the anvil to cut the tape;
- and
- n. tape drive means for advancing the bulk strip across the anvil and into the path of the tape handling member.
