Abstract: A fuel door status indicating system for a pressurized fuel system is provided. The status indicating system includes pressure sensing means configured to measure a pressure in the fuel system, a controller operatively connected to the pressure sensing means and configured to compare a measured fuel-system pressure with a predetermined pressure, and a display operatively connected to the controller and configured to provide an indication as to whether the fuel door may be opened. The controller is configured to control operation of the display to provide the indication responsive to the comparison of the measured pressure with the predetermined pressure.

Abstract: A web cutter for a surface winder provides a cutting blade which is moved into position adjacent the web and held stationary during cutting of the web. A web deflector is mounted for rotation about the axis of the drive drum on the opposite side of the web from the knife and when in the cutting position, deflects the web into the knife for severing the web. The device includes a guide shoe supported adjacent the knife for deflecting the severed edge of the web around the new core to be wound.

Abstract: A surface winder and roll changing mechanism includes primary arms rotatable through 360.degree. between a substantially horizontal initial position where a new core can be loaded, a second position where the primary arms transfer the new core with the roll being formed thereon to secondary arms, and an intermediate position between the initial and second positions in which the web is cut and started on the new core, the primary arms being rotatable in one direction to return them to the initial position. In one embodiment, a grab knife is carried by the primary arms, and the web cutting knife is separately mounted on the frame, while in a second embodiment, both the grab knife and the cutting knife are carried by the primary arms. A single cutting knife or a reciprocating double cutting knife assembly may be used in either embodiment.

Abstract: A moving web of material having a high tendency to elongation under stress, such as woven and non-woven plastic fiber or filament webs, is cut by the combined action of a cutting knife which executes its cutting stroke generally in line with and upstream of the web and a grab knife which holds the web at a station spaced closely downstream from the path of the cutting knife and thereby isolates the small length of web between the two knives while the cutting knife completes its stroke.
