Description

FIELD

Embodiments of the present disclosure generally relate to the field of counting of corrugations in a material. More specifically, embodiments of the disclosure relate to a pleat counter and methods for accurately counting a number of pleats in a corrugated sheet of material to be used for the production of air filters.

BACKGROUND

An air filter designed to remove particulate matter from an airstream generally is a device comprising fibrous materials. These fibrous materials may remove solid particulates such as dust, pollen, mold, and bacteria from the airstream. Air filters are used in applications where air quality is important, notably in building ventilation systems and with engines.

Air filters may be used in automobiles, trucks, tractors, locomotives and other vehicles that use internal combustion engines. Air filters may be used with gasoline engines, diesel engines, or other engines that utilize fossil fuels or other combustible substances. Air filters may be used with engines in which combustion is intermittent, such as four-stroke and two-stroke piston engines, as well as other types of engines that take in air continuously so that a combustible substance may be burned. For example, air filters may be used with some gas turbines. Filters may also be used with air compressors or in other devices that take in air.

Filters may be made from pleated paper, foam, cotton, spun fiberglass, or other known filter materials. Generally, the air filters used with internal combustion engines and compressors tend to be comprised of either: paper, foam, or cotton filters. Air filters for internal combustion engines prevent abrasive particulate matter from entering the engine's cylinders, where it would cause mechanical wear and oil contamination. In many fuel injected engines, a flat panel pleated paper filter element may be used.

Air filters may be manufactured from a continuous roll of pleated material. It is essential that assembled air filters have a predetermined number of pleats. For example, suppose an air filter is to be tapered. A manufacturer may calculate the number of pleats needed by taking into consideration the size of the air filter and the height of the pleat. A piece of material that includes the desired number of pleats may be cut from the roll. Once cut, the piece of material may be joined at its ends to form a sleeve which is then formed into a filter medium of the air filter.

Along an assembly line, the desired number of pleats generally is counted manually and marked at each interval where the desired number repeats on the roll. As will be appreciated, manually counting pleats not only is time consuming, but is also subject to error. The likelihood of such errors generally is increased by the tedious nature of the job. If the number of pleats is improperly counted, a faulty air filter will result. A need exists, therefore, for a pleat counter that accurately counts the number of pleats in a corrugated sheet of material to be used for the production of air filters.
