ABSTRACT:
A collator apparatus is disclosed for assembling a plurality of continuous forms into a sequence of multi-layer forms. The apparatus includes a numbering device which is disposed adjacent to the sequence of forms for applying a number to a first form of the sequence. The device includes a numbering wheel having an axis of rotation disposed normal to a direction of movement of the sequence of forms past the wheel, the wheel defining a peripheral surface. A printing device is secured to the peripheral surface for printing the number of the first form when the printing device contacts the first form during mutual movement of the printing device and the first form. A locking mechanism is operably connected to the wheel for selectively locking the wheel against rotation thereof. The locking mechanism locks the wheel in a first rotational disposition of the printing device until the first form reaches a first location relative to the first disposition. A driving device is drivingly connected to the wheel for rotating the wheel from the first disposition when the first form reaches the first location. The arrangement is such that the wheel is rotated by the driving device at a peripheral speed which is the same as a linear velocity of the first form past the numbering device so that the printing device prints the number on the first form when the printing device reaches a second rotational disposition thereof. A further driving device is drivingly connected to the wheel for accelerating rotation of the wheel to complete one revolution of the wheel. The arrangement is such that when the revolution of the wheel is completed, the locking mechanism again locks the wheel against further rotation thereof so that the printing device is in the first disposition thereof until a second multi-layer form of the sequence reaches the first location.
