Abstract:

A method and apparatus for high speed web processing incorporating linear tools with rotary motion to provide the advantages of linear and rotary type processing as herein disclosed. The web processing apparatus of the present invention includes a pair of linear processing tools, a plurality of sets of rotary gears, a drive shaft coupled to a first set of rotary gears, and a plurality of brackets connecting the linear processing tools to the remaining sets of rotary gears. The drive shaft of the present invention drives movement of the linear processing tools at the same rate that a web to be processed moves in between the linear processing tools. Accordingly, the linear processing tools engage one another at a flat angle at a fixed position of the web to process the web. The present invention also discloses a method for high speed web processing wherein a pair of linear processing tools are bracketed to a plurality of rotary gears such that the linear processing tools rotate with the rotary gears. A pair of linear processing tools are aligned such that the upper and lower linear processing tools engage at a flat angle when the lower linear tool is at its uppermost position and the upper linear tool is at its lowest position. A web of material is guided in between the upper and lower linear processing tools at the same rate at which the linear tools are rotated. In this manner, a web of material is processed when the upper and lower linear processing tools engage the web at a flat angle.
