Web-fed printing machine having a register device for aligning the paper web

A web-fed printing machine having a framework and two cylinders which form a printing nip for a web;

• means for directing the web through the nip including a register device for aligning the web, said device including an infeed roller and a discharge roller which guide the web;
• means for controlling the position of said infeed roller and discharge roller comprising an actuating device;
• web-edge sensors for sensing the edge of a web;
• said register device being responsive to signals from said web-edge sensors;
• said infeed roller being positioned upstream of said nip and said discharge roller being positioned downstream of the nip;
• said web-edge sensors being positioned on both sides of the nip, means for displacing said infeed roller and discharge roller relative to said framework of the printing machine in a plane running through the axes of said rollers;
• said actuating device having actuating members for individually adjusting said rollers;
• means for mounting said rollers for individual displacement in the direction of their axes of rotation and for pivotable movement into an oblique position;
• a web-feeding device positioned upstream of said web-directing device;
• said web-feeding device, on its infeed side, being pivotally mounted about a spindle, said spindle being mounted in a stationary manner in said machine framework and positioned in a plane which is oriented perpendicularly with respect to the axis of said infeed roller and at least approximately intersects said infeed roller in the center thereof, and said web-directing device and said web-feeding device being connected to one another.
