Abstract: A passive treadmill having a governor mounted upon one end of a treadmill roller to adjustably limit the rate of speed of the treadmill belt. Resilient flexible rotating springs flex due to the centrifugal force developed during rotation, the magnitude of the centrifugal force being a function of the linear speed of the treadmill belt. Arcuate shaped brake pads mounted on integral projections of the flexible springs move into sliding engagement with an annular stationary surface to limit the linear speed of the treadmill belt. A rotatably mounted cam is manually adjustable to adjust the spacing between the aforesaid slidably engagable surfaces to adjust the operating speed. A stabilizing ring arranged between the governor springs prevents the projections from resonant non-uniform flexing.Support rollers rollingly support the treadmill belt, and are rotatably mounted within elongated openings provided in each of a pair of mounting rails.

Abstract: A passive treadmill having a governor to adjustably limit the rate of speed of the treadmill belt. Resilient flexible rotating blades flex due to the centrifugal force developed during rotation, the magnitude of the centrifugal force being a function of the linear speed of the treadmill belt. Brake pads mounted on the flexible blades move into sliding engagement with an annular stationary surface to limit the linear speed of the treadmill belt. A rotatably mounted cam is manually adjustable to adjust the spacing between the aforesaid slidably engageable surfaces to adjust the governor. The governor assembly is of relatively small size and volume and the moving components of the governor are mounted within a compact casing.The rollers, which rollingly support the treadmill belt, are rotatably mounted within elongated openings provided in each of a pair of mounting rails.

Abstract: A butt splicing unit for cutting a web running from a depleting roll and splicing the end of a supply web to the cut end of the running web. The unit includes a rectangular stationary knife and two moveable knife members below and on each side of the stationary knife. Each of the moveable knives cooperate with one of the knife edges formed by the lower corners of the stationary knife. Above the stationary knife, is a pair of vacuum plates for holding the end of a supply web. Each of the knife members includes a body having a vertical leading surface facing in the direction of the running web. Each of the leading surfaces are provided with vacuum ports for holding the lower portion of a strip of tape thereto. A knife blade is mounted at the top of each of the knife members and a recess is provided between one end of the blade and the body to receive the upper portion of the tape strip to hold it out of contact with the running tape.

Abstract: The splicer successfully lap splices web material being drawn from a roll under low tension. A central stationary knife member extends transversely of the web and splicing carriages on either side of the stationary knife are slideably mounted to be moved perpendicular to the web toward and away from the knife member. Each carriage includes a roller for directing the web past the splicing mechanism, a knife blade for cooperating with the knife member to cut the web, a clamping pad for engaging the side of the knife member for clamping web therebetween during a splice, and a pressure pad for impacting against the pad of the other carriage to press the webs to opposite sides of a strip of adhesive tape to form the splice.

Abstract: An expandable device for locking an annular core to a shaft for rotation therewith in which an annular body mounts on the shaft and carries a plurality of radially movable bars overlying a single-wall annular bladder lying against the surface of the body. The bars are positioned side by side around the circumference of the body and are interconnected by linking members to limit radial movement. An annular notched band is secured to the body of each end of the bars and engages recesses therein to transmit torque between the bars and the body. Pressurized air is introduced between the bladder and the surface of the body to force the bars radially outward to grip the core.

Abstract: Web from a depleting roll of web in use is directed along a vertical line by rollers. A knife member is mounted for movement across the line and has a knife edge on its lower surface to cut the web. Vacuum ports are provided on each side of the knife member to hold the end of a spare roll which is trimmed flush with the knife edge. A piece of tape is applied to and overlaps the end of the spare web. The spare web end is positioned on the side of the knife member facing away from the line. A pair of cutting plates are positioned on opposite sides of the line below the knife and are movable vertically. Tape pressing bars are pivoted to the plates. The plate on the opposite side of the line from the knife is positioned with its top edge aligned with the knife edge. The other plate is spaced from the knife edge so that the bar acts against the tape applied to the spare web end.

Abstract: A five spindle turret rewinder wherein the turret is driven in steps so that each spindle successively dwells in each of five stations. A core is manually placed on the spindle at the first station. At the second station, heat liquified glue is applied to the core while the spindle is slowly rotated. At the third station, web leading to a filled roll at the fourth station is severed and applied to the glued core while heat liquified glue is applied to the back side of the web above the cut line. The web is wound onto the core at the fourth station. The spindles are driven rapidly at the third and fourth stations. The glued cut end of the web is pressed against the filled roll by a brush at the fourth station. The filled roll is automatically removed from the spindle at the fifth station.
