Abstract
To ensure a uniform formation in packets with a predetermined number of elements, of sheet-like elements, for example, paper handkerchieves, two counter-rotating bodies are provided, presenting movable blades which, cooperate to receive each sheet-like element coming from a feeding group. Each pair of blades lays down a sheet-like element on a packet to be formed, on its turn supported by fins carried by belts or chains vertically moving downward, starting from the counter-rotating bodies and synchronically with the latter, in such a way that the packet to be formed lowers until the desired number of elements is received, and it is then ejected parallel to the axes of the rotating bodies.
Claims11
A device for gathering sheet-like elements, at least cut to size and optionally folded, in reciprocal superimposition to form packets having a predetermined number of sheet-like elements, the device comprising in combination:
- (a) feed means for feeding said sheet-like elements at a constant speed and at constant intervals in a predetermined direction;
- (b) distributing means for receiving said sheet-like elements from said feed means, and for vertically laying said sheet-like elements being received in superimposition to form a packet of a predetermined number of said sheet-like elements, and said distributing means comprising:
- (1) a pair of counter-rotatable spaced parallel bodies, each having a corresponding plurality of planar straight projecting blades arranged for receiving each sheet-like element on a respective pair of said blades and for feeding each sheet-like element to form said packets by synchronous rotation of said counter-rotatable spaced parallel bodies,
- (2) a motion-transmitting means associated with each counter-rotating body, with a driving gear located below each counter-rotating body also associated with said each motion-transmitting means, for operatively moving each motion-transmitting means between said counter-rotating body and said driving gear, and each motion-transmitting means having a plurality of projecting fins, each capable of cooperating with a corresponding projecting fin of the other of said motion-transmitting means to form a means for supporting said packets being assembled, and
- (3) the fins, when horizontally aligned, being spaced from adjacent fins of the same motion-transmitting means by a distance equal to the height of the packets having a predetermined number of sheets to be formed, and the fins being arranged to be synchronized, when in the movement, with the movement of the blades of said counter-rotating bodies, and wherein the distance between two adjacent fins in the vertical direction is equal to n times the step between the blades of the counter-rotating bodies, with n being the number of sheet-like elements to form each packet;
- and
- (c) drive means associated with said feed means and said distributing means for feeding said sheet-like elements at a constant speed and frequency, and for driving said counter-rotating bodies at constant and equal angular speeds, one with respect to the other, and with the frequency of feeding the sheet-like elements being determined by the angular speed and the number of blades of the counter-rotating bodies, and in coordination with the movement of the blades.
