A filament feed monitor and method of remediating a printing error in a 3D printer is provided. The method may include detecting motion of a trailing gear by an optical sensor. The printing error may be detected by a controller connected to the optical sensor in response to a determination that rotational motion of a filament feed roller has exceeded a predetermined threshold, which may be determined based on the detected motion of the trailing gear. A command may be generated and executed by the controller to remediate the printing error.

A fiber width adjusting apparatus includes a rotary body. The rotary body is configured to rotate around a rotation axis while interposing a sheet-shaped fiber, and cause, by frictional force generated between the rotary body and the sheet-shaped fiber, force to act on the sheet-shaped fiber while feeding the sheet-shaped fiber in a feed direction to vary a width and an orientation angle of the sheet-shaped fiber. The sheet-shaped fiber is impregnated with a resin or is before the impregnation with the resin. The rotation axis is parallel to a thickness direction of the sheet-shaped fiber. The force contains a component that is in a direction perpendicular to the thickness direction and to the feed direction.

A cable feed device for feeding a cable to a cable processing machine includes a first rotatable roller and a second rotatable roller for guiding the cable such that the cable can be arranged in a loop around the first roller and the second roller, and a cable drive for transporting the cable. The first roller is arranged stationary, wherein the second roller can be pushed or pulled away from the first roller with a force, wherein the second roller has a first state and a second state, wherein the second roller is locked in a first position in the first state and is moved in the second state by the force such that the distance between the first roller and the second roller changes depending on the length of the cable between the two rollers.

A roller assembly for a taping device includes a roller body defining a central bore, a bushing configured to be received within the central bore and rotationally fixed to the roller body, and a shaft configured to be disposed within the central bore. The shaft defines an outer surface that extends through the bushing. The shaft has a boss that extends radially outward from the outer surface. A resistance element is disposable within the central bore is configured to contact the bushing and the boss in a manner providing an amount of rotational resistance between the roller body and the shaft when the roller assembly is in an assembled configuration.
