Abstract
The present invention teaches an improved apparatus and method for pleating air filter assemblies. The improved apparatus is a rotary pleater which includes a belt and pulley system to facilitate movement of pleated filter media and reduce snags and jams. The apparatus is further modular and portions may be separated in order to provide easier access to the inner workings of the device to conduct maintenance or remove jammed or snagged filter media. Finally, the machine and the methodology embodied in the machine, pre-cuts the filter media into sections prior to pleating of the section(s).
Claims9
An improved rotary pleating machine having a belt and pulley system comprising:
- an upper and a lower pleat head shaft;
- an upper and a lower belt shaft;
- an upper belt assembly operating in conjunction with said upper pleat head shaft and said upper belt shaft;
- and,
- a lower belt assembly operating in conjunction with said lower pleat head shaft and said lower belt shaft.
A modular rotary pleating machine for pleating filter media comprising
- a roller frame having a track therein;
- a first unwinder, puller and cut section positioned on said roller frame and a having a projection seated in said track;
- a second pleat head section positioned on said roller frame and having a projection seated in said track;
- and,
- a third bunching and finishing section positioned on said roller frame and having a projection seating said track;
- wherein said sections may be either in contact or moved apart on said roller frame.
An improved rotary pleating machine having a means to cut filter media, being unwound into the machine, to a pre-determined length.
A method of pleating air filter media, said method comprising the steps of:
- unwinding a roll of filter media and pulling said media into a rotary pleating machine;
- measuring and cutting a portion of said filter media based upon pre-determined criteria to produce a section of media;
- pleating said section of media through the use of a plurality of rotary pleat heads;
- moving said section of media from said pleat heads to a bunching section through the use of a belt and pulley system;
- and,
- sizing said pleats and completing the pleating process.
