Strap feed assembly with floating back-up wheels |
摘要 |
A strap feed assembly has a drive wheel driven by a reversible electric motor to feed and tension a strap around an item and wherein a back-up wheel assembly imposes a tension force on the strap by use of multiple floating wheels which are arranged to spring bias and float with respect to a strap and apply a tension force thereto across an extended strap area to reduce pressure on the strap so as to prevent it from being bent or deformed whereby a consistent strap feed is maintained.
