    • A tensioner (28) for controlling tension in a continuous web (12) being wound onto a rewind roller (30) after the web (12) is processed, for example after printing on labels carried on the web. The tensioner (28) receives the web (12) from a processor (10) and has a slack sensor (38) between the processor (12) and the input of the tensioner (28). The slack sensor (38) indicates when the slack is a selected minimum, and the web (12) is clamped by the tensioner (28). After a selected time, which is before the slack sensor (38) indicates a maximum slack is present, the motor (34) driving the rewind roller (30) is stopped and the web (12) is undamped. After unclamping the web, the rewind roller (30) is again driven at a speed to take up more of the web (12) than that which is driven by the processor (10), to wrap the web (12) around the rewind roller core (32) until the slack sensor (38) indicates the slack in the web (12) is at a minimum.
    • 用于控制连续幅材(12)中的张力的张紧器(28)在幅材(12)被处理之后被卷绕到重绕辊(30)上,例如在打印在卷筒纸上的标签上之后。 张紧器(28)从处理器(10)接收幅材(12),并且在处理器(12)和张紧器(28)的输入之间具有松弛传感器(38)。 松弛传感器(38)指示松弛度是选定的最小值,并且腹板(12)被张紧器(28)夹紧。 在松弛传感器(38)指示出最大松弛之前的选定时间之后,驱动回绕辊(30)的马达(34)停止,并且卷筒纸(12)未被阻尼。 在松开卷筒纸之后,再卷绕辊(30)以一定的速度被驱动以吸收比由处理器(10)驱动的卷筒纸(12)更多的卷筒纸(12),以将卷筒纸(12)包裹在卷绕辊 (32)直到松弛传感器(38)指示幅材(12)中的松弛为最小。
