Abstract
Apparatus for applying a flexible strap to an article, such as a roll of paper product, in a predetermined position with respect to a surface on the article, such as an end face of a roll, and in proper alignment with the end face to prevent loosening of the strap at a later time. A generally plate-like guide member has a strap guide surface thereon and a strapping head for feeding the strap around the guide surface for engagement with the article to be strapped. The guide member is mounted on linear bearings for translation with respect to a support frame. A spherical bearing is interposed between the linear bearing and the guide member to allow the guide member to be skewed with respect to the linear bearings to align itself with the end face or other surface on the article to be strapped. A series of pressure fluid piston and cylinder actuator positioning devices are mounted on the guide member and are engageable with the end face or other surface of the article to be strapped for proper positioning of the guide member and the strap for application to the article. The guide member is moved in opposite directions by two stage pressure fluid cylinder and piston actuators which may be actuated to center the guide member on the machine between two conveyors for the article, an upstream position and a downstream position for application of a strap to one or more ends of the article.
