It is desired to prevent misalignment of the edges of a folded sheet by smoothly feeding the sheet while keeping tension fluctuations to a minimum when the sheet is unwound from a paper roll (R) set in a paper feed unit to a packaging unit even though the paper roll diameter decreases gradually as the sheet is unwound. A core pipe (P) for a sheet roll is provided comprising a hollow core pipe having a predetermined length for winding a sheet therearound, and magnets (24) provided on the inner periphery of said hollow core pipe near one end thereof at angular intervals determined such that the amount and diameter of the sheet roll wound therearound can be calculated by an angle sensor (25) provided on a fixed shaft (1b), said hollow core pipe being rotatable together with a hollow shaft (1c) rotatably mounted around said fixed shaft. Accordingly, the sheet tension is adjusted to an optimum, constant level by controlling the sheet braking force stepwise according to the roll diameter measured by the sensors.

In einem Verfahren zur Identifikation der Spinnstellen von Kops wird jeder Kops mit einer individuellen Markierung versehen, mit welcher die jeweilige Spinnstelle identifiziert werden kann. Die Markierung wird im Bereich der Umspulstationen ausgelesen um die jeweilige Spinnstelle festzustellen. Sie kann z.B. aus einem Strichcode (9) bestehen, der auf ein Ende der Spinnhülse (7) aufgebracht wird. Mit diesem System wird es in einfacher Weise möglich, in der Umspulmaschine gemessene Garnparameter den jeweiligen Spinnstellen zuzuordnen.

It is desired to prevent disalignment of the edges of a folded sheet by smoothly feeding the sheet while keeping tension fluctuactions to a minimum when the sheet is unwound from a paper roll (R) set in a paper feed unit to a packaging unit even though the paper roll diameter decreases gradually as the sheet is unwound. A sheet length measuring sensor or rotary encoder is provided in the paper feed path through which the packaging sheet unwound from the paper roll is fed toward the packaging unit. An angle sensor (25) is provided which comprises Hall element sensors provide on a support shaft and magnets provided on a core pipe of the paper roll. Any change is the signals from one of these sensors relative to the signal from the other sensor is used to calculate the paper roll winding length, and the sheet tension is adjusted to an optimum, constant level by controlling the sheet braking force stepwise according to the roll diameter measured by the sensors.

The invention relates to a reel (5) provided with a packaging material (7). The reel (5) is adapted to be mounted on a mandrel (2) of a filling machine (1). The reel (5) is hollow and has the shape of a cylinder, an inner portion of which is provided with a tag (6) containing information at least associated with the packaging material (7). The invention also relates to a filling machine (1) for filling a packaging material (7) with a food product.
