摘要:
The invention relates to a system for supplying a web of packaging material to a packaging machine, the system comprising: a motor (14) rotating a roll (16) of a web of packaging material (12), a conveyor conveying the web (12) from upstream to downstream. The system is characterized in that it further comprises the system further comprises a dancer (36) located downstream of the roll (16) and upstream of the conveyor, the dancer (36) being movable between first and second positions based upon a change in tension of the web (12), and a control circuit (154) controlling the motor (14) and being in communication with at least one sensor (56) sensing the position of the dancer (36), wherein the control circuit (54) controls the motor (14) to rotate the roll (16) to thereby cause the dancer (36) to move from the first position to the second position, wherein the control circuit (54) calculates a starting speed of the motor (14) based upon the movement of the dancer (36) from the first position to the second position, and further wherein the control circuit (54) controls the motor (14) at the calculated starting speed to begin supplying the web (12) to the conveyor.

Die Erfindung geht aus von einem Verfahren zum Vereinzeln von Gegenständen (4) aus einem Stapel (6) in einen Gegenstandsstrom (8), bei dem die Gegenstände (4) mit einem Abzugsmittel (14) vom Stapel (6) abgezogen und einander überlappende Gegenstände (4) mit einem Trennmittel (20) voneinander getrennt werden. Zum Erreichen einer zuverlässigen Vereinzelung mit einer geringen Doppelabzugsrate wird vorgeschlagen, dass beidseitig des abgezogenen Gegenstands (4) jeweils mehrere Zugmittel (Z 1 - Z' 12 ) des Trennmittels (20) am Gegenstand (4) angreifen und mit unterschiedlicher Vortriebsgeschwindigkeit (v 1 - v' 12 ) in Transportrichtung (12) betrieben werden.

Dans un dispositif d'alimentation en articles de courrier destiné à être monté en amont d'une machine à affranchir et comportant au moins une zone d'alimentation en articles de courrier (10) pour recevoir une pile d'articles de courrier supportés par une pluralité de rouleaux d'entraînement (16) et une zone de séparation (18) pour effectuer une sélection individuelle de ces articles de courrier, il est prévu des moyens de commande (30) pour commander une variation de la vitesse de rotation de la pluralité de rouleaux d'entraînement lorsqu'en sortie de la zone de séparation une mesure d'un intervalle séparant deux articles de courrier successifs diffère d'une valeur d'intervalle prédéfinie d'un seuil de correction prédéterminé.

摘要:
A method and an arrangement for feeding out end sheets from a stack of sheets comprises that a driver acting against the end sheet of the stack (1) first displaces the end sheet in the plane thereof toward a support for elastic bulging of the end sheet, and then displaces the buckled end sheet away from the support, to a separating arrangement for the separation of sheets that unintentionally are accompanying the end sheet (21) fed out. The driver being carried by a spring arrangement, which offers an increasing support force to the driver upon the advancement of the stack by means of a pusher acting against the rear end of the stack. A sensor detects the displacement position of the driver, and activates the driver for a sheet-outfeed operation when the distance sensor detects a displacement position of the driver corresponding to a predetermined abutment force of the driver against the end sheet. Between the sheet-outfeed operations, the pusher is unloaded.
摘要:
The invention relates to a method for controlling a circumferential register in a web-fed rotary press, according to which an actual value pertaining to a tension (51-55) of a web (03) passing through the printing units (04, 06, 07, 08) is determined, and an angular position and/or an angular velocity of a cylinder (12, 16) of a first printing unit (04) with regard to a cylinder of a second printing unit (06) is changed according to this determined tension. The correction of a register offset ensues without controlling the tension (51-55) and without the use of an optical recognition system by determining the value of the necessary change for the angular position (Δζ) and/or the angular velocity (Δζ) as a function of the measured tension (51-55) of the web (03).
