Abstract
Abstract A machine for forming and delivering cellulose tissues by cutting and folding several juxtaposed layers and then delivering the tissues to a collecting device. Means are provided for conveying tissues from the folding cylinders to a conveyor at one speed in horizontal position and delivering the formed tissues in a vertical position at a relatively lesser speed to the collecting device.

Claim 1
Independent Claim
255 words
Apparatus for the depositing of soft objects in a vertical position, especially folded-together cellulose tissues which are delivered at a high speed, then braked to a lower speed than the delivery speed, and then deposited; said apparatus consisting of at least one endless conveyor belt movable at a high linear speed, means for depositing said objects with their leading edges in predetermined uniformly spaced relation to each other onto said conveyor belt, a deposit cylinder rotatable in the same direction as the direction of movement of said conveyor belt, but at a lesser peripheral speed than the linear speed of the conveyor belt, said deposit cylinder having mounted on the periphery thereof circumferentially spaced deposit baskets disposed substantially tangentially to said periphery and adapted to receive the objects delivered from said conveyor belt, said baskets having bottoms spaced uniformly about the periphery of said deposit cylinder, the ratio of the linear speed of the conveyor belt to the peripheral speed of the deposit cylinder being equal to the ratio of The spacing of the leading edges of the objects from each other to the spacing of said basket bottoms from each other, including a drive shaft for driving said deposit cylinder, a pulley for said conveyor belt, said pulley being mounted on and rotatable about the axis of said drive shaft but driven independently of said drive shaft, the diameter of said pulley being smaller than the diameter of said deposit cylinder to an extent at least equal to the thickness of the conveyor belt.
Claim 2
Dependent Claim
255 words
Apparatus for the depositing of soft objects in a vertical position, especially folded-together cellulose tissues which are delivered at a high speed, then braked to a lower speed than the delivery speed, and then deposited; said apparatus consisting of at least one endless conveyor belt movable at a high linear speed, means for depositing said objects with their leading edges in predetermined uniformly spaced relation to each other onto said conveyor belt, a deposit cylinder rotatable in the same direction as the direction of movement of said conveyor belt, but at a lesser peripheral speed than the linear speed of the conveyor belt, said deposit cylinder having mounted on the periphery thereof circumferentially spaced deposit baskets disposed substantially tangentially to said periphery and adapted to receive the objects delivered from said conveyor belt, said baskets having bottoms spaced uniformly about the periphery of said deposit cylinder, the ratio of the linear speed of the conveyor belt to the peripheral speed of the deposit cylinder being equal to the ratio of The spacing of the leading edges of the objects from each other to the spacing of said basket bottoms from each other, including a drive shaft for driving said deposit cylinder, a pulley for said conveyor belt, said pulley being mounted on and rotatable about the axis of said drive shaft but driven independently of said drive shaft, the diameter of said pulley being smaller than the diameter of said deposit cylinder to an extent at least equal to the thickness of the conveyor belt.
Claim 3
Dependent Claim
240 words
Apparatus for depositing soft objects in a vertical position, especially folded together cellulose tissues which are delivered at high speed, than braked to a lower speed than the delivery speed, and then deposited; said apparatus consisting of at least one endless conveyor belt, means for moving said conveyor belt at a relatively high linear speed, means for positioning said objects with their leading edges in predetermined uniformly spaced relation to each other onto said conveyor belt, a shaft, a deposit cylinder fixedly mounted on said shaft for rotation therewith, means freely mounted on said shaft in non-obstructing relation with said cylinder supporting said conveyor belt and rotatable therewith, means for rotating said shaft and cylinder in the same direction as the direction of movement of said conveyor belt and at a lesser speed than the linear speed of said conveyor belt, said deposit cylinder having mounted on the periphery thereof circumferentially spaced deposit baskets deposited tangentially to said periphery and adapted to respectively receive the objects delivered from said conveyor belt, said baskets having bottoms spaced uniformly about the periphery of said deposit cylinder to receive sequentially the respective leading edges of said objects when moved by said conveyor belt at a relatively higher speed in said uniformly spaced relation, thereby reducing the speed of said objects as they are received in said deposit baskets to be turned by the deposit cylinder in position to be deposited in vertical position.
Claim 4
