Title: Improvements in or relating to ruling machines
IPC: B41G3/00
Filed: 1923-10-29
Abstract: .232,644. Hinterdorfer, F., and Rona, J. Oct. 29, 1923. Ruling-machines.-A sheet-ruling machine. comprising a ruling-roller 1 and an impression cylinder W, is provided with means for preventing portions of the sheet from being ruled consisting of two strips H. N reciprocated tangentially to the impression cylinder, one strip H covering a heading space on the sheet, and the other strip N having projecting tongues 3, so that lines of different lengths are ruled on the sheet. The strip H is attached to a rod 13 mounted in brackets 7 on a crosspiece 6a carried by angle parts 6 adjustably mounted on carriages 4 reciprocated in guides 5 of the machine frame. Brackets 11<a>, fixed to the crosspiece 6<a>, carry jaws 9 holding the strip N to which are glued strips of paper to form the projecting tongues 3. The ends of the strips H, N are supported by a plate B<x> on a slide 16 which is reciprocated to and from the ruling roller by devices on the carriage 4. A spring 18<a>, on a bolt 18 fixed to the carriage, causes the slide 16 to move forward until its front end engages a stop 20, whereupon the carriage 4 continues its movement until a spring pawl 19 on the slide snaps into a notch 22 on the carriage. Engagement of the pawl 19 with the notch 22 causes the slide 16 to move back with the carriage 4 until the pawl is disengaged by a stop 23. As the strips H, N approach the ruling devices, the roller 1 lifts to allow the strips to pass between it and the impression cylinder. When the strips reach the forward end of their travel, the roller 1 drops and the strips begin to move backward. Meanwhile, a sheet is carried by endless bands D from a table A<1> to the ruling devices, means, such as are described in Specification 174,619, being provided to ensure that the sheet reaches the ruling position at the requisite time for the desired blanks in the ruling to be obtained. The strips H, N may be adjusted relatively to the ruling roller by devices comprising a bolt and nut 12 for adjusting the angle piece 6 on the carriage 4, nuts 13<a> for adjusting the strips H in the brackets 7, and a bolt and nut 11 for adjusting the jaws 9 on the brackets 11<a>, these devices being accessible for operation during the running of the machine.
