each perforation having a diameter of approximately 0 312 inches rotation of cylindrical member 2 about cylindrical member 1 is created by providing a variable speed motor 8 engaging a drive sprocket 10 which in turn is intended to functionally engage roller chain 35 circumscribing outer cylinder 2 at sprocket 6 typically the drive motor can be approximately 3 4 horsepower while relative movement between outer cylinder 2 and inner cylinder 1 is facilitated by virtue of bearing member 4 obviously bearing 4 provides a substantial impediment to the flow of air such that low pressure drawn within inner hollow non rotating cylindrical member 1 will draw air through perforations 13 in said outer hollow rotating cylindrical member 2 it is an essential element of the present invention to provide a configuration whereby can shaped objects 21 are to be maintained by means of air drawn through perforations 13 on the surface of rotating cylinder 2 only in a specific predetermined arc of rotation such as shown in fig3 ideally the arc of rotation is approximately 90 u00b0 whereby can shaped objects 21 are received from the surface of air conveyor 16 having topmost horizontal surface 18 and slots 17 for the directional discharge of air therethrough turning again to fig3 cans 21 are to be received from horizontal surface 18 having a substantially vertical orientation in a 34 12 o 39 clock 34 position cans 21 are then caused to adhere to the perforated rotating surface of cylindrical member 2 until can shaped objects 21 reach a 34 3.
