Abstract: A method of forming container end panels from a sheet of material includes inserting the material into a press at a first level, blanking the material at that level, passing the material through a die and preliminarily forming it in a continuous stroke but at a second level and transferring it laterally at the second level for reforming and curling. The apparatus includes blanking and forming tooling at a first station and reforming and curling tooling at second and third stations. The reforming and curling tooling is disposed at the second level and the first, second and third stations are interconnected by an endless, apertured belt also disposed at the second level. An alternative embodiment involves disposing the first station tooling at an angle with respect to the press centerline, feeding the material into the press in a first direction and moving the preliminarily formed ends in opposite directions normal to the feed direction to second and third stations disposed on opposite ends of the press.

Abstract: An adjustable locked center and dynamic tensioner include both a method for setting tension in a belt or chain drive system and apparatus for setting the friction torque so as to match the system setting torque. The method includes forcing the tensioner against a stable mounting surface with sufficient spring load that a target friction torque will be required to rotate the tensioner. The tensioner arm is then rotated into the belt or chain until, when the setting torque is removed, the belt or chain will counter rotate the tensioner arm and the target friction torque in the tensioner will cause the target setting tension to remain in the system. The apparatus includes a tensioner arm pivotally mounted on a fixed surface with a spring engaging the arm and being clamped against the fixed surface. Modifications include introducing a compliant coupler such as an elastomeric bushing or spring between the stable mounting surface and the tensioner arm.

Abstract: A double-belt conveyor band with a continuously revolving conveyor band, the belt of which is supported on a band feeder and in connection with a steep segment on trough roller assemblies, and is supported flatly on the steep segment, as well as with a continuously revolving covering band. The belt is buckled in the conveyor seam for the formation of closed conveyor spaces, preferably between traction reinforcements positioned externally, the shear-resistant lateral reinforcements acting in cooperation therewith. The belt ends are pressed on one another and the longitudinal edges of the belt are held together. It is provided in accordance with the invention that, in order to hold together the belts on both longitudinal edges of the cover band, fasteners projecting externally are provided with opposing apertures to which the longitudinal edges of the conveyor belt, during the running of the trough roller assemblies, approach or move away from during the running of the conveyor belt.
