Abstract: A web guiding and centering apparatus for guiding and centering a moving web of substantially constant width relative to a fixed center line includes two guiding devices positioned equally distant from the selected center line, each guiding device comprising a pair of co-acting guide rolls inclined in the direction of travel of the moving web for engaging an edge portion of the web on opposite faces thereof. One guide roll of each pair is pivotally and resiliently biased toward the other roll of the same pair about a pivot which is outboard of the web. At least one roll of each pair has a composite surface which includes an outboard surface portion of relatively hard, low coefficient of friction material and an inboard surface portion of a relatively soft, high coefficient of friction material.

Abstract: An idler roller assembly is provided which permits angular adjustment of the idler roller relative to the housing of the punch press feed so that accurate tracking of the feed stock may be accomplished. The idler roller rotates within a frame that is supported by trunions within the housing of the feed. The trunions permit pivoting of the frame to move the idler roller toward and away from the driven roller of the feed. An eccentric adjustment is provided between one of the trunions and the housing of the feed so that minute angular adjustments may be made to the idler roller.

Abstract: A magnetic card transport system for an electronic typewriter comprises a reversible drive roller and a coacting pinch roller which form a nip through which a magnetic card is passed. The drive roll and pinch coact to move the card in opposite directions. A guide surface is provided which is engaged by one longitudinal edge of the card, and guide springs are provided which engage the other longitudinal edge of the card to urge the card into engagement with the guide surface for registration purposes. The pinch roll is mounted in such a manner that it may freely oscillate. The oscillation is such that the pinch roll axis pivots in each direction from a line substantially perpendicular to the guide surface between 1/2.degree. and 3.degree. about a vertical axis normal to its axis of rotation to allow for self-alignment to maintain the card in alignment with the guide surface.

Abstract: A magnetic card transport system for an electronic typewriter comprises a reversible drive roll and a coacting pinch roll which form a nip through which a magnetic card is passed. The drive roll and pinch roll coact to move the card in opposite directions. Guide means are provided which is engaged by one longitudinal edge of the card, and spring means are provided which engage the other longitudinal edge of the card to urge the card into engagement with the guide means for registration purposes. The pinch roll is mounted in such a manner that it may freely oscillate. The oscillation is such that the pinch roll axis pivots in each direction from a line substantially perpendicular to the guide means between 1/2.degree. and 3.degree. about a vertical axis normal to its axis of rotation to allow for self-alignment to maintain the card in alignment with the guide means.

Abstract: A cast piece guide roll segment in continuous casting equipment having a curved cast piece guide path which is used in the structure for supporting the roll groups in the respective curved portions for guiding the cast piece leaving the mold along the curve between the vertical and horizontal paths. In view of the problems inherent in continuous casting equipment such as the need for frequent roll changes and emergency shut-downs, the roll segment disclosed includes roll units having at least a pair of rolls and bearings provided at opposite ends thereof and removable from a frame, on which frame are mounted pivotable caps for holding roll units.

Abstract: A magnetic card transport subsystem for an electronic typewriter comprises a reversible drive roll and a coacting pinch roll which form a nip through which a magnetic card is passed. The drive roll and pinch roll coact to move the card in opposite directions. The pinch roll is so mounted that it can rock and be self-leveling to permit the full width of the pinch roll to engage the card and uniformly distribute pressure thereto. A mechanism for adjusting the pinch roll for alignment purposes is also provided.
