摘要： The device comprises two or more cover plate members (14), whose lengths are submultiples of the lengths of a range of platen rollers (12) and such that two or more plate members disposed in side-by-side relationship cover the entire length of the platen roller. Each plate member (14) comprises a lower guide portion (16) of part-cylindrical shape and two wall portions (17, 18) which are substantially planar and set at different angles of inclination, being connected to the lower guide portion in such a way as to lead in a sheet of paper (19) towards the guide portion. Each plate member (14) is pivotally mounted on a control shaft (22) which is parallel to the axis of the roller (12) and capable of preventing transverse movements of the plate member with respect to the roller, and carries the usual paper pressing rollers (34,36) which are disposed in two parallel rows. A leaf spring (26) co-operates with a lug (24) on the plate member (14) to hold the paper pressing rollers pressed against the platen roller. The control shaft comprises opening cams (57) arranged to co-operate with the leaf springs to disengage same from the respective lugs and to permit the respective plate members to drop away from the platen roller (12), whereby the paper pressing rollers (34, 36) are disengaged from the platen roller to assist in introducing the sheet of paper.

摘要： Apparatus for facilitating printer paper feeding. The apparatus is made up of a yoke and a platen channel carrying a paper aligner and feed rollers. The yoke has downwardly extending legs with a detent therebetween. The apparatus is rotatably positionable on a rod mounted parallel to the platen, and the detent is for accepting the rod. The downwardly extending legs are for cooperating with a tooth of a rotatable comb for causing rotation of the apparatus on the rod. The channel serves as a paper deflector and guide for guiding paper about the platen. Within the channel are openings through which front and rear feed rollers carried by the channel extend. Also within the channel is an aligner opening for accepting the paper aligner which is positionable within the aligner opening. The paper aligner has a downwardly extending leg for cooperating with another tooth on the comb to position the aligner within the aligner opening. Due to the structure of the apparatus, a member thereof can be utilized and positioned on the rod to accommodate any length platen.

摘要： A paper infeed for printers or typewriters comprises a cylinder (30) and a number of guide rollers (380, 382), by means of which the paper sheet is guided round the cylinder (30) during the infeed. Provided underneath the cylinder (30), next to the guide rollers (380, 382), is a number of slideably displaceable plates (404), the surface of which is shaped according to the curvature of the cylinder (30). During the paper infeed, the plates (404) are displaced in the circumferential direction of the cylinder (30) towards the side of the cylinder facing a printing head, so that the paper sheet is further guided round the surface of the cylinder (30) by means of the plates (404). After the conclusion of the paper infeed, the plates (404) are returned to their normal position on the underside of the cylinder (30), in which they do not impede the printing operation.

摘要： In the illustrated embodiment, a guide element is provided in advance of the platen-pressure roller gap for the purpose of preventing creasing of thin papers during transport. The guide element may have a retracted position providing for unobstructed movement of the paper leading edge along an insertion channel and into the platen-pressure roller gap. Then during paper transport by the platen, the guide element is shifted to an active position for deflecting the paper toward the platen such that the paper contacts the platen in advance of the pressure roller over a substantial angle (e.g. 15 DEG -20 DEG ). A spring for urging the guide element to active position may have a spring force more insufficient to substantially deflect thick types of paper not subject to creasing.

摘要： A pressure roller bar for ink recording devices is disclosed wherein the rollers are formed with ink absorbing surface portions. The roller may have a synthetic body with a circumferential recess receiving a replaceable felt ring which projects radially outwardly of remaining portions of the roller.

摘要： 795,155. Typewriters &c. SIEMAG FEINMECHANISCHE WERKE GES. Jan. 4, 1956 [July 23, 1955], No. 238/56. Class 100(4) In a paper guiding device for typewriters &c. comprising at least two parallel sets of paper-pressing rollers 1a-b, 2a-d, mounted on a paper trough 4, eccentric rollers 3a, b which roll on the platen are mounted on the trough outside the paper conveying path and coaxial with one of the sets of paper pressing rollers. The trough and the pressing rollers, which are urged against the platen by spring 6, are raised periodically by the eccentric rollers to prevent crumpling &c. of the paper. At the position of their smallest radius rollers 3a-b are bored, as at 9, so that when the trough is lowered the rollers rotate into positions in which the portions of greatest radius are lowermost.
