Abstract
Abstract A device for handling of laminar objects, particularly for laying-out newspapers to a pile, comprises a supply grate horizontally movable to-and-fro in the direction towards and above a receiving surface for the pile and away therefrom, packages of newspapers being successively delivered on said supply grate which moves them to a position above said receiving surface, means being provided for depositing said packages of newspapers on said receiving surface upon initiation of the retracting movement of the supply grate away from said receiving surface.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
255 words
A device for piling up a stack of flat objects comprising: stack support means; first drive means for controllably lifting and lowering said stack support means; means defining a stationary object support and a movable object support, said movable object support having an upper and a lower side and being extendable to and withdrawable from a position overlying said stack support means; said stationary support having an edge extending to and substantially contiguous with said movable object support when said movable object support is in said overlying position; second drive means for controllably moving said movable object support; conveyor means to convey said objects along a path of travel extending across said stationary object support and said movable object support, abutment means to engage said objects on said upper side of said movable object support and to hold said objects in position when said movable object support is being withdrawn from its overlying position, said first and second drive means and said conveyor means being operable to extend said movable object support to said overlying position, to convey said objects along said path of travel, to lift said stack support means until the stack being formed abuts against and is pressed by said underside of said movable object support, to withdraw said movable object support from said overlying position while the objects are being held in position by said abutment means and upon withdrawal of the movable object support are delivered onto the stack, and to lower said stack support means towards its lowermost position.
Claim 2
Independent Claim
255 words
A device for piling up a stack of flat objects comprising: stack support means; first drive means for controllably lifting and lowering said stack support means; means defining a stationary object support and a movable object support, said movable object support having an upper and a lower side and being extendable to and withdrawable from a position overlying said stack support means; said stationary support having an edge extending to and substantially contiguous with said movable object support when said movable object support is in said overlying position; second drive means for controllably moving said movable object support; conveyor means to convey said objects along a path of travel extending across said stationary object support and said movable object support, abutment means to engage said objects on said upper side of said movable object support and to hold said objects in position when said movable object support is being withdrawn from its overlying position, said first and second drive means and said conveyor means being operable to extend said movable object support to said overlying position, to convey said objects along said path of travel, to lift said stack support means until the stack being formed abuts against and is pressed by said underside of said movable object support, to withdraw said movable object support from said overlying position while the objects are being held in position by said abutment means and upon withdrawal of the movable object support are delivered onto the stack, and to lower said stack support means towards its lowermost position.
Claim 3
Dependent Claim
53 words
A device as claimed in claim 1, in which said movable object support is a gridlike structure movable back and forth and guided in a horizontal plane parallel to the plane of the objects, the abutment means including pivotally mounted stops adapted to penetrate into the path of movement of said gridlike structure.
Claim 4
Dependent Claim
42 words
A device as claimed in claim 1 comprising means for interrupting the movement of the stack support means towards said lower side of the movable object support upon attainment of a predetermined application pressure between the movable object support and said stack.
Claim 5
Dependent Claim
74 words
A device as claimed in claim 1 comprising a second stack support means, said movable object support including a delivery fork arranged for rectilinear movement back and forth from a middle position situated between said two stack support means over one or the other thereof, said abutment means comprising pivotally mounted stops associated with each of the stack support means and being adapted to penetrate into the path of movement of said delivery fork.
Claim 6
Dependent Claim
32 words
A device as claimed in claim 4, in which said stops are constituted as abutment rakes with teeth which in operative position engage from below between the teeth of said delivery fork.
Claim 7
Dependent Claim
29 words
A device as claimed in claim 1, in which said stack support means includes a conveyor means which can be selectively operated, depending on the height of the pile.
Claim 8
Dependent Claim
52 words
A device as claimed in claim 4, in which the stack support means not swept by the delivery fork is liftable to at least the level of the delivery fork, in order to remove the stack deposited on said stack support means in the same plane in which the objects are supplied.
Claim 9
Dependent Claim
47 words
A device as claimed in claim 2 comprising a driver associated with said gridlike structure to act on one of the lateral edges of the objects to be supplied and displaceable back and forth in the same direction and at the same rate as said gridlike structure.
