Abstract: In accordance with the present invention an automatic paper roll loading mechanism intentionally produces a slack on the surface of a paper roll, indirectly senses the leading edge of the paper of the roller via the slack, and conveys the leading edge to a preselected stand-by position. The mechanism is therefore capable of automatically paying out the paper even when a mark is absent at the leading edge. This allows not only a fresh paper roll but also a half-used paper roll to be automatically loaded.

Abstract: A device has a pivoted lever for detecting a near end state of a roll of paper, and the lever is held at a first position by the weight of a roll of paper, but is resiliently biased toward a second position by a spring. When the roll of paper does not have a core, and when the weight thereof falls to a predetermined value, the lever is moved from the first position to the second position due to a resilient force of the spring. When the roll of paper has a core, and when a diameter thereof is reduced to a predetermined value, the lever receives the roll of paper in a recess formed therein, and is moved from the first position to the second position due to a resilient force of the spring. When the lever is moved to the second position, this is detected by a suitable detecting element. Thus, the detector can detect the near end state of the roll of paper without regard to whether the roll of paper has a core or not.

Abstract: A turntable has a drive for rotating it. A vertical control rod extending up alongside the turntable carries a dancer arm adjustably mounted thereon. The strip coming off the supply coil trains over the spool. A variable electrical control is adjacent the control rod and influenced by its rotary position. The control relates the speed of the turntable to whether the arm is inward or outward--whether there is greater or less demand for the strip. In the preferred version, a bias for the control rod urges the dancer arm outward in dampened fashion but more readily permits the arm to be drawn inward.

Abstract: When an operator manually rotates flanges for holding roll paper, flange placement rollers rotate accordingly. Paper is supplied from the roll paper, and rotational force of one of the flange placement rollers is transmitted to a drive roller by a gear mechanism.

Abstract: An apparatus is illustrated for unwinding a web, such as cloth or paper, which utilizes a driven belt having a width in excess of the width of the web forming a cradle for a cloth roll and the like with elements for adjusting the path of travel of the belt including at least one elongated oscillatable roll over which the belt passes and which is oscillated responsive to elements for sensing the position of the belt. The method contemplates doffing the core of the cloth roll by utilizing a vertically movable roll for tightening the belt while at the same time lowering one of a pair of spaced rolls supporting the cradle so that the core roll rolls off the belt and the belt is positioned for receiving a full cloth roll thereon prior to lowering of and cushioning by the movable roll to form the cradle in the belt.

Abstract: An end of media detection system is provided for a system which unrolls a media supply such as paper from a cylindrical core substrate. One (trailing) edge of the media is attached to the core substrate. As part of the media detection system, a shaft which is positioned within a pair of cradles supports the cylindrical core. One of the cradles houses a plastic slide, which in turn acts vertically on the actuator of a microswitch when the shaft is in place. The weight of the shaft and media roll acting on the microswitch keeps the microswitch in an inactive state, however, as the media on the roll is played out, at some point just before the media is exhausted the shaft is moved upward due to the adhesive attachment of the trail edge of the media to the core substrate. Movement of the shaft relieves the pressure on the actuator of the microswitch thereby actuating the microswitch to send a signal to a controller to stop rotation of the shaft.

Abstract: One or both of the lap rollers on which a lap roll is mounted for unwinding purposes is driven with an increasing speed during the winding-off interval so as to maintain the thickness of the lap layer constant. This, in turn, maintains the count of the sliver to be formed in the comber at a constant number. The increase in the lap roller drive can be made dependent upon the length of the lap layer which is unwound from the roll, on the mass of the lap layer delivered to the comber or on the mass of a sliver produced from the combed lap as measured at a point downstream of the comber. The speed may be increased in a stepwise manner or continuously.
