Abstract: A daisy wheel spring disc utilized in conjunction with a daisy wheel print element to control impression. Both the spring disc and the print element have radially extending petals. The print element petals carry a character adjacent their outer extremity. A spring disc petal is associated with each print element petal for which impression is to be controlled. The spring disc petals vary in length relative to the print element petals. The lengths of the spring disc petals depend upon whether the character on the associated print wheel petal has a large or small print surface area. During printing, the spring disc is positioned on the printing side of the print element. When a print element petal is driven out of the plane of the remaining print element petals during printing of a character, the associated spring disc petal will be contacted and will absorb a portion of the energy imparted to the print element petal.

Abstract: The continuous type belt (3) is arranged round two rollers (25), one of which is driven. One straight section of the type belt (3) contacts over its entire length the support designed as a platen (23). In order to avoid grooves on the platen (23) caused by the rotating type belt (3), and to achieve a distribution of other kinds of wear of the platen (23) over its circumference, a gear motor (27) causes the platen (23) to rotate very slowly (approximately 1 revolution in 72 hours). The platen (23) can also be rotated without gear motor. For this purpose, the longitudinal axis of the platen (23) is slightly inclined relative to the edge of the type belt (3). This inclination effects a small movement component in the direction of the platen circumference while the type belt (3) slides along the lateral surface of the platen (23), said component causing a slow revolution of the platen (23).

Abstract: In a typewheel printer, a radial spring disk is provided which has the same pitch as the type wheel and which is subdivided into fingers. One spring disk finger is associated with each type wheel finger. The spring disk fingers are of different length, depending upon whether the character on the associated type wheel finger has a great or small character line length. GE9-78-018
