The present invention relates to systems and methods for calculating the additional local stretching of a moving web through a converting process in order, during rewinding, to find the position of defects in the web that were identified during winding and stopping the web with the web defect close to or at a defect correcting station. The method comprises, during rewinding of the web, the steps of detecting position markers (PM(n)) applied during winding of the web (5), measuring the distance between the position markers, calculating the additional local stretching between the position markers occurring during rewinding, applying the calculated additional local stretching to the known position of a following web defect to determine an estimated position of that web defect in the rewinding web. A method for correcting a web defect comprises the step of subsequently stopping the web with the web defect at, or close to, a defect repairing station (38).

A device and a method for making a wireless connection between a paper sensor in a roll holder and a printing device which receives a printing medium from the roll holder, in which a magnet arranged on the roll holder performs, with each turn of the pin of the roll holder, a cyclical movement which includes first a lifting of the magnet, caused by a rotation of the pin by a fraction of a turn, and then a fall by gravity of the magnet which falls near a coil which is energized by the mechanical energy of the magnet for supplying electrical energy to an emitter in wireless communication with a receiver to receive a signal with each revolution of the pin to count the revolutions made by the pin and act as a paper sensor.

A sheet supply device includes a supporter, a rotation device, a guide, a support shaft, a biasing member, a sensor, a roller, and control circuitry. The sensor is disposed to protrude from the facing portion toward the roll and biased in a direction to contact the outer peripheral surface of the roll. The sensor outputs a detection signal at a level corresponding to an amount at which the sensor protrudes from the facing portion. The roller is supported by the facing portion, to contact the outer peripheral surface of the roll at a position different from a position of the sensor in a circumferential direction of the roll. The control circuitry controls the rotation device based on a signal change rate that is a change amount of the level of the detection signal per unit time. The control circuitry causes the rotation device to rotate the spool in the winding direction, and stops an operation of the rotation device when the signal change rate based on a change in relative positions between the outer peripheral surface and the sensor without passage of a leading end of the sheet through the position of the sensor does not exceed a predetermined reverse set threshold value.

A container for a machine for dispensing individual blister cards from a coiled strip of blister cards, each of the blister cards housing a medicament or medical item, includes: a housing including a receptacle with an internal compartment and a lid, the receptacle configured to receive the coiled strip of blister cards in the internal compartment; a drive mechanism mounted to the housing; an outlet in the housing; and a controller operatively connected with the drive mechanism. The drive mechanism is configured to receive signals from the controller to selectively drive a single blister card from a strip of blister cards residing within the compartment through the outlet.

A sheet feeder includes a support to support a roll sheet winding a sheet, a sensor that is at a first position on the support and contacts a surface of the roll sheet to detect a level difference at a trailing edge of the roll sheet and output a first signal and a second signal, a roller that is at a second position different from the first position in a circumferential direction of the roll sheet on the support and contacts the surface of the roll sheet to guide the roll sheet, and circuitry to cause the roll sheet to rotate in a sheet feeding direction to feed the sheet, and detect the trailing edge of the roll sheet based on the first signal output from the sensor, and the second signal output from the sensor.
