Abstract

In a device for collating sheets of paper having at least one receiving surface made from electrically insulating material, a set of rolls for feeding a sheet from one side of the receiving surface and depositing it thereon and an improved charge remover for removing electrical charges from a deposited sheet comprising at least one conductor connected to earth potential which is disposed on the side of the insulated receiving surface remote from the side where the sheet enters and which forms an abutment with which the leading edge of each sheet comes into contact when it is being deposited on the insulated receiving surface, thereby removing electrical charges from the entire sheet.

Claims

1. In a device for collating sheets of paper, having at least one receiving surface made from electrically insulating material, a means to feed a sheet from one side of the receiving surface and deposit it thereon, and a means for removing electrical charges from the deposited sheet, the improvement comprising at least one conductor connected to earth potential and being disposed on the side of the insulated receiving surface remote from the side where the sheet enters to form an abutment with which the leading edge of the sheet containing concentrated electrical charges comes into contact when it is being deposited on the insulated receiving surface, thereby removing the electrical charges from the entire sheet.

2. The device as described in claim 1 wherein the conductor comprises a plurality of conducting abutments along the edge of the insulated receiving surface disposed in a spaced relationship adjacent to one another.
