US Patent 7134258 Packaging apparatus and methods

A packaging system includes a transport defined by a linear motor driving independent elements in a path to carry out a packaging function. The elements are driven independently of other elements in the path and are driven by the linear motor in a section of the path under the influence of an external axis signal from an operably adjoining packaging function to register and synchronize the elements in position and time with a moving component or event of the adjoining function in a downstream direction. Method and apparatus are disclosed.
