摘要： A pile of sheets arranged vertically next to one another is gently urged against a rigid metal plate that can be reciprocated back and forth very rapidly so as to pull the end sheet off the pile by suction and to return to rest against the pile of sheets before they have followed this reciprocation motion to the same extent as the end sheet. Once the plate pulls rapidly away from the end of the pile, pulling the end sheet with it, this end sheet is engaged by a suction roller and pulled laterally off the pile.

摘要： The device for picking and transporting components of different size has a gripping casing (1) which comprises a plurality of concentrically arranged, axially movable gripping elements (4, 8, 11). The elements move telescopically relative to each other, and each have a suction opening arranged at the end and connected, according to the working position, with a vaccuum inlet (3). For picking up a small part, only the innermost, smallest gripping element operates. In picking up a middle-size part, the innermost gripping element (11) and the middle gripping element (8) work together, while in the gripping of a large part, the outermost gripping element (4) is additionally actuated.

摘要： An envelope-stuffing machine adapted to insert sheets of paper or the like into an envelope or a folder comprises a pair of opposite perforated surfaces connected to a suction chamber and between which the envelope or folder is introduced so as to draw the opposite sides of the envelope or folder apart to receive the sheets to be inserted. A pressure sensor is provided to respond to the suction in the chamber communicating with the perforations of the surfaces to trigger the insertion of the sheets upon the detection of a predetermined reduced pressure in the chamber. The pressure sensor is of the threshold type.
