    摘要： The forms are particularly endless forms having transversely extending lines of perforations. The press includes printing mechanisms having plate cylinders carrying plates extending through part of their circumferential peripheries, an equalizing carriage adapting web-shaped printing material, fed intermittently from a supply loop thereof, to the peripheral speed of the plate cylinders and executing a return movement during the printing interval, rolls carried by the equalizing carriage and looped by the printing material, and a main traction device, adjustable to the form length, with a main traction roll driven intermittently in the direction of traction and cooperable with pressure rolls. Printing means are provided either on the printing plates or on relatively adjustable rings on the plate cylinders to print adjusting marks on the printing material at the leading and trailing ends of each form length. Preferably the two marks on each form length are at respective different distances from an edge of the form, and are linear marks aligned with the respective form length ends to be perforated.

    摘要： A decurling method and the associated apparatus are usable with a printing system or the like incorporating a series of stations for performing operations upon a web as the web is advanced in predetermined registered relationship with the stations. An elongated decurling member over which the web is drawn imparts to the web a tendency to curl which compensates for an objectionable curl tendency imparted to the web by the system or curl tendency previously existing in the web. The relative positions of the web and the decurling member are adjustable in a manner which produces change in the magnitude of the compensating curl tendency imparted to the web without influencing the path length of the web.
