Abstract: The invention relates generally to a roofing shingle apparatus and more particularly to an improved such apparatus for high speed shingle making generally when handling a double shingle line (one line overlaid on the other with the high side of each line on opposite sides to make a single mostly even thickness) in a more compact arrangement from the cutter to the stackers and catchers, but not limited to a slower single line of shingle making that uses a flipper at the discharge of the catcher shuttle and not limited to a four wide overlaid to four thicknesses of shingles in one line and scissor cut, not described in detail herein, before entering a single line delivery belt section.

Abstract: A pipe conveyor may include a conveyor belt formed into a pipe-like shape to define a space that contains material to be transported by the conveyor. Along at least a portion of the pipe conveyor, friction drive conveyors or friction tires may be positioned. The friction drive conveyors may include friction drive belts that engage the pipe conveyor belt. Via this engagement, the friction drive conveyors apply a force to the conveyor belt that moves the conveyor belt in a desired direction. Further, when the friction drive conveyors or friction tires are positioned within an inclined vertical section of the conveyor belt, the friction drive conveyors or friction tires vertically lift the pipe conveyor belt via pushing the conveyor belt in a vertical direction, thus assisting a drive pulley that vertically pulls the conveyor belt and material transported on the conveyor belt from a lower elevation to a higher elevation.

Abstract: A dynamic temporary storing device for articles like syringes and similar articles is situated between an outlet of a first machine and an inlet of a second machine. In the dynamic temporary storing device, two pairs of side-by-side belts transfer articles from an outlet of said first machine downstream to an inlet section of an article conveying path. The articles are gathered, one after another, to form groups of articles in the inlet section. The conveying path ends with an article outlet section situated near the inlet of the second machine. Driving means are associated to the conveying path and pass at adjustable time intervals through the inlet section so as to pick up said groups of articles and move them along the conveying path up to the outlet section. Then the groups of articles are transferred them to the inlet of said second machine. Changes in operation rate of the second machine are compensated by changing the number of articles in each group or by changing the length of the conveying path.

Abstract: The invention concerns a conveying device for sheet steel plates and for moving several sheets (1, 1?) inside or through a working zone (W; 50) wherein the sheets are machined. The inventive feeding device comprises first and second sheet feeders (10, 11; 20) which feed the sheets in controlled manner to the working zone (W) so that the sheets are machined with positional accuracy. The first sheet feeder (10, 11) is located on an input side of the tool zone and the second sheet feeder (20) is located on an output side of the tool zone. The two sheet feeders (10, 20; 11; 20) are mutually synchronized in their movements (x, y) when feeding forward the sheet (1), the sheet driven by the synchronous movement being maintained by the two sheet feeders. The invention provides the advantages of increased speed and safety. It is possible to increase the speed without the sheet being deformed or losing its flatness.

Abstract: A device for controlling the conveyance of particulate material on a conveyor belt comprises a frame with an endless belt attached thereto. The apparatus is positioned above the conveyor belt and in frictional contact therewith whereby the motion of the conveyor results in motion of the endless belt on the apparatus. The particulate material thereby is passes between the endless belt and the conveyor belt and any bouncing movement of such material is prevented. Use of the present invention on conventional conveyor belts controls the dispersion of the particulate material carried thereon and allows for the speed of the conveyor to be increased. The present invention is suitable for use with a conveyor apparatus used with a truck and commonly known as a “stone slinger”.

Abstract: An assembly for conveying stacked documents includes a conveying surface extending along the conveying path and a conveyor roller that is suspended opposite to the conveying surface for movement between positions at different distances from the conveying surface. In the operating condition, the conveyor roller exerts a press-on force. The assembly also includes a transmission for driving the conveyor roller. The transmission is coupled with the conveyor roller in such a manner that if a couple is exerted on the conveyor roller in the conveying sense, a force directed against this press-on force is exerted on the conveyor roller. As a result, the temporary increase of the couple and the temporary reduction of the circumferential speed of the conveyor roller is limited.
