ABSTRACT:
An apparatus for applying an adhesive padding to a tack strip substrate composed of the following elements: (a) a conveyor for conveying a substrate along an elongated path; (b) an arm disposed above the conveyor, pivotable about an axis, biased to a first position, disposed so that the arm comes in contact with the substrate as the substrate is being conveyed along the elongated path by the conveyor, and adapted to be moved from a first position to a second position when brought in contact with the substrate; (c) a feeding device, disposed over the conveyor, for feeding to the substrate along a first path an adhesive strip and removing a removable backing therefrom along a second path; (d) a cut-off device having a movable part for cutting said adhesive strip, the movable part adapted to be moved from a first position above the substrate to a second position below the substrate and biased to the first position; (e) an activator connected to the movable part of the cut-off device and adapted to momentarily move the movable part from its first to its second position by applying a force thereto in response to the arm being returned to its first position and thereafter releasing the force, thereby permitting the movable part to return from its second to its first position; and, (f) a drive mechanism and a clutch, the drive mechanism in mechanical engagement with the clutch, the clutch normally not in engagement with the feeding device, but adapted to be placed in mechanical engagement therewith, the clutch being responsive to the arm being moved from its first to its second position to become engaged with the feeding device.
