Implementations of a material roll dispenser for holding and dispensing rolls of materials are provided. In some implementations, the material roll dispenser comprises one or more configurations of a roll dispensing assembly, a platform assembly, a handle assembly, and a wheel assembly each configured to telescopingly position and secure onto a vertical member to form the material roll dispenser.In some implementations, a method of using the material roll dispenser comprises telescopingly positioning and securing the roll dispensing assembly, the platform assembly, the handle assembly, and the wheel assembly onto the vertical member to form the material roll dispenser. In some implementations, the method of using the material roll dispenser further comprises loading, holding, and dispensing one or more rolls of material from the material roll dispenser.

A method for continuously producing a cleaning member obtained from a multilayer web that includes at least a fiber bundle with hollow fibers, and non-woven fabric strips includes at least: a step for preparing a guide member provided with a pair of width-adjusting member, and having a predetermined interval; a step for conveying a fiber bundle strip, such as the fiber bundle with hollow fibers, between the pair of width-adjusting members of the guide member, and adjusting the width of the fiber bundle strip so as to match the aforementioned interval; a step for forming the multilayer web by overlaying the strip-like fiber bundle, the width of which has been adjusted, on the non-woven fabric strips; and a step for joining the components of the multilayer web.

A method of continuously producing a cleaning member obtained from a multilayer web that includes at least a fiber bundle and a non-woven fabric, includes the following steps: preparing a guide member provided with a pair of width-adjusting members having a predetermined interval therebetween; conveying a fiber bundle through the pair of width-adjusting members of the guide member to adjust the width of the fiber bundle strip so as to match the aforementioned interval; forming the multilayer web by overlaying the fiber bundle, the width of which has been adjusted, on the non-woven fabric; and joining the fiber bundle and non-woven fabric.

A press roller spring frame is provided. The spring frame includes a frame body having a first section having an arcuate shape, a second section extending from the first section and having a substantially planar shape, a third section extending from the first section and having a substantially planar shape. The second and third sections are configured to oppose one another with the first section therebetween. The spring frame further includes a roller operatively coupled to the third section and configured to rotate about an axis. A compressive force may be applied to the roller to displace the third section closer to the second section, whereby the arcuate shape of the first member is compressed. The compression causes the first member to produce a spring force that resists the compressive force applied against the roller to keep the roller against the object applying the compressive force.

An optic connector cleaning apparatus includes a driving assembly, a cleaning tape and a casing. The driving module includes a reel assembly. The cleaning tape includes a first surface and a second surface opposite the first surface, the cleaning tape winds at the reel assembly; the casing includes an inverting structure and a cleaning region. The cleaning tape winds about the inverting structure. The first surface of the cleaning tape is exposed to the cleaning region, the cleaning tape winds about the inverting structure to expose the second surface through the cleaning region.

A communication line such as an optical fiber or cable is attached along a wall, ceiling, trim piece, or other selected surface on or inside of a building, by paying out the fiber from an applicator tool while the tool guides the fiber along the selected surface. The outer surface of the fiber is prepared so that the fiber will be in a temporarily tacky condition when the fiber is pressed onto the selected surface by the applicator tool. The fiber is pre-coated with an adhesive that is activated by a fluid supplied by the applicator tool. As the applicator tool presses the fiber onto the selected surface, the activated adhesive coating on the fiber quickly becomes non-tacky to attach the fiber firmly to the surface.

A 360-degree freedom electric cord device system contains and manages automatic extension and retraction of an electric cord/cable supplying power to a push/pull-type electric machine, either self-propelled or not, for intended displacement or steering on a surface by a user. The 360-degree freedom electric cord device system, partly mounted on the electric machine, allows the power cord to clear obstacles on the surface and includes a self-retracting spool to automatically extend and rewind the power cord and continuously keeps physical tension therein, in a straight line and a natural position, during the displacement in any direction of the electric machine. With a ratchet mechanism, the device can also suitably be used independently of the machine as an electric retractable extension cord reel.

For pushing packages (7) from a winding mandrel (4) of a takeup apparatus (1), an ejector is provided, which has a piston arranged for reciprocating movement in a cylinder (8) by supplying a pressure medium. The piston is a magnetic piston, whose polarity is opposite to that of at least one magnet connected to a push unit (9). The push unit (9) is displaceable substantially along the cylinder (8) with the movement of the piston.
