Abstract

Abstract The apparatus, according to the invention, comprises essentially a container (10) wherein is arranged a pile (11) of objects (12) to be distributed. A friction drive wheel (13) is mounted at the end of a lever (14) pivoting about an axis (15). An inclined ramp (21) is arranged downstream of the objects to be distributed. The upper part of the ramp is provided with a staircase-shaped recess (26) and is prolonged by a plane surface (22) which defines with a plane surface (23) parallel therewith a guiding channel (25) for guiding the objects (12).

Claim 3
Dependent Claim 45 words
An apparatus according to claim 1, wherein the support means comprises a height-adjustable platform which is connected to a rotary screw and nut adjustment device operable for raising the platform to maintain a substantially constant height of the top of a said stack, when present.
Claim 4
Dependent Claim 46 words
An apparatus according to claim 2, wherein the adjustable platform is pivotably about a horizontal axis of a support carried by the adjustment device, and the platform is biasable against a bottom surface of a said stack, when present, by a spring resting on the support.
Claim 5
Dependent Claim 42 words
An apparatus according to claim 1, wherein the friction drive means comprises at least one friction wheel rotated by a drive mechanism, and the friction wheel is mounted on a free end of a lever and is pivotable about a fixed axis.
Claim 6
Dependent Claim 52 words
An apparatus according to claim 1, wherein the guideway comprises a slot formed by the first surface of the upper guide plate and a second surface connected with the upper portion of the ramp, and the second surface is disposed substantially parallel to and at a predetermined distance from the first surface.
Claim 7
Dependent Claim 37 words
An apparatus according to claim 5, wherein the predetermined distance is slightly greater than the thickness of one of the objects to be dispensed and less than the thickness of two of the objects to be dispensed.
Claim 8
Dependent Claim 20 words
An apparatus according to claim 1, wherein the step-like recess comprises two successive recesses which are staggered along the ramp.
Claim 9
Dependent Claim 34 words
An apparatus according to claim 1, further comprising means for raising the objects to be dispensed so that a said object to be dispensed is constantly located adjacent the lower portion of the ramp.
Claim 10
Independent Claim 249 words
An apparatus for individually dispensing flexible laminar objects in succession from a stack, said apparatus comprising: support means for supporting a said stack; a guide unit defining a path to be followed by each object to be dispensed, the path comprising a guideway and a ramp located between the support means and an entrance of the guideway dimensioned to accommodate a single said object at a time, the ramp being inclined with respect to the guideway, the ramp having an upper portion situated adjacent the entrance of the guideway and a lower portion situated to receive the topmost object of a said stack, when present, and the guideway having a first surface defined by an upper guide plate which extends over an upper portion of the ramp; at least one friction drive unit disposed above the support means and having friction drive means which engages the top surface of a said stack, when present, for conveying the topmost object thereof along the path; a two successive recess disposed in and staggered along the upper portion of the ramp and forming a stop adjacent the entrance of the guideway; wherein during operation of said friction drive unit, a front edge of a said topmost object, when present, is carried along the path by sliding along the ramp and is brought into contact with the upper guide plate at the entrance of the guideway, and a said topmost object is deflected into the guideway by sliding along the upper guide plate.
