Abstract
The invention consists of bonding a strip of pile fabric to a plastic tube which is mounted over a mandrel, by an adhesive substance. The adhesive substance may take many forms, and heat derived from a multitude of heat sources, such as infra red, radio frequency, open flame, quartz, induction, ultrasonic or a plasma jet may be used to ensure a good bond between the plastic tube and the pile fabric.
Claims12
In a method of producing a structurally integrated paint roller, the method comprising the steps of:
- providing a plastic paint roller core,
- rotating the paint roller core,
- providing an adhesive substance in strip form which is compatible with both the paint roller core and a fabric backing,
- said strip form adhesive substance being composed solely of said adhesive substance,
- heating the strip form adhesive substance to a temperature at which it will bond to the paint roller core,
- presenting a fabric strip to the paint roller core, the fabric strip having a fabric backing,
- making a single-application of the strip form adhesive substance to the rotating paint roller core immediately prior to the placement of the fabric strip on the paint roller core in an amount sufficient to securely bond the fabric strip to the paint roller core so as to yield a structurally integral product, and
- wrapping the fabric strip while the adhesive substance is in a bondable condition about the paint roller core while the fabric strip and paint roller core are rotating with respect to each other.
In a method of producing a structurally integrated paint roller, the method comprising:
- providing a thermoplastic paint roller core,
- rotating the paint roller core,
- providing an adhesive substance which is compatible with both the paint roller core and a fabric backing,
- said adhesive substance being in a hot, extruded conditions in the form of an envelope which envelopes the paint roller core,
- said envelope form adhesive substance being composed solely of said adhesive substance,
- presenting a thermoplastic fabric strip to the paint roller core, the fabric having a fabric backing,
- applying the hot, extruded envelope adhesive substance to the rotating paint roller core immediately prior to the placement of the fabric strip on the paint roller core in an amount sufficient to securely bond the fabric strip to the paint roller core so as to yield a structurally integral product, and
- wrapping the fabric while the adhesive substance is in a bondable condition about the paint roller core while the fabric and the paint roller core are rotating with respect to each other.
