Abstract
A strapping device (100, 100') for strapping one or more articles, comprising a tensioning apparatus (1) for tensioning the strap around the articles, a joining apparatus (2) for joining two overlapping portions of the strap, and a strap conveying apparatus (5) comprising one or more transport rollers (51, 52) for conveying the strap, the strap conveying apparatus comprising an encoder roller (53) configured to contact the strap and a roller rotary encoder (54) configured to monitor the encoder roller and to output an encoder signal, wherein the device comprises a controller (4) connected with the roller rotary encoder and configured to receive the encoder signal, to determine a speed of rotation of the encoder roller using the encoder signal, and to compare the speed of rotation of the encoder roller to a speed of rotation of the transport rollers.
