Claims
- 1. An apparatus for use in connection with a system employing a plurality of drums having varying circumferences for applying a portion of a continuous length of innerliner material to a selected one of said drums comprising:
- (a) transport means including a suction manifold moveable longitudinally generally horizontally in a forward direction for transporting said innerliner material from said continuous length to said drum and being moveable generally vertically towards and away from said drum for applying one end of said innerliner material to said drum, said suction manifold being moveable in a longitudinal rearward direction for stretching said innerliner material after said one end has been applied to said drum and prior to application of a second end of a remaining portion of said innerliner material to said drum by said suction manifold;
- b) cutting means for severing a portion of said innerliner material from said continuous length;
- c) measuring means for measuring the angular displacement of said drum and providing an output thereof;
- d) calculating means for calculating the length of innerliner material required to completely wrap around the drum based upon the measured angular displacement of said drum;
- e) centering means for centering the innerliner material with respect to said drum after said one end has been applied to the drum by the suction manifold and prior to the suction manifold applying the second end of the remaining portion of said innerliner material to said drum; and
- f) control means in communication with said measuring means and calculating means for causing said cutting means to sever a portion of said innerliner material from said continuous length, said portion being shorter than the circumference of the smallest drum in the system, and for causing said innerliner material to be stretched by the suction manifold before it is applied to said drum and for causing said suction manifold to transport said stretched portion of innerliner material toward said drum and to apply said stretched portion to said drum.
