Abstract: A mechanism for controllably advancing web material of indeterminate length, such as paper from a roll, according to a predetermined format and at different speeds. The format information is carried by an endless tape which is normally driven in synchronism with the web and which controls electromagnetic drive clutches and a brake through electronic circuitry. The operation of the brake and clutches controls the distance that the web travels from the generation of a stop signal until the web is actually stopped, and also regulates the longitudinal force on the paper, by controlling the acceleration and deceleration, to prevent tearing when the web is started, stopped, or when the speed of the web is changed. The format tape may be advanced to the format heading independently of the web drive by clutch means for disengaging the format tape from the synchronous drive and by engaging a small motor for independently driving the tape. The tape stops at its format heading automatically as a result of a control signal developed from the tape itself.

Abstract: A method of oscillation-free print hammer and return is provided in an apparatus having an inertial hammer, a relay and a resilient backstop. In this method the armature of the relay is pivotably mounted and imparts motion to the hammer. The solenoid of the relay physically restrains the motion of the armature and then holds the armature by residual magnetism. The hammer continues in inertial flight until it reaches the printing area. On rebound the hammer strikes the armature and part of the kinetic energy of the hammer is absorbed as the hammer drives the armature free from the residual magnetic field. The armature and hammer continue to the backstop which absorbs or dissipates the remainder of the kinetic energy. The absorption of kinetic energy is for damping hammer oscillations and permits higher frequency of operation.
