Abstract
A method of attaching an end cap to a filter member begins with a step of providing a first plastic end cap configured to fit on an end of a filter member. The next step in the method is heating the end cap to soften an inner surface thereof. The preferred method of heating the end cap involves applying infrared heat to the cap without contacting it. The next step in the method according to the invention is contacting the filter member with the heated surface of the end cap. Preferably the end cap is pressed into place against the filter member, using an appropriate machine, and applying enough force to partially embed the end of the filter member into the molten plastic. The next step in the method involves holding the end cap in place against the filter medium until the end cap cools sufficiently for the material thereof to stiffen, causing the filter member to adhere thereto.
