Embodiments of the invention include apparatus and methods for coating drug coated medical devices. In an embodiment, the invention includes a coating apparatus including a coating application unit. The coating application unit can include a fluid applicator having a lengthwise axis and a width. The fluid applicator can include a tip comprising a first face across the width of the fluid applicator. The first face of the fluid applicator can be oriented at an angle of from about 15 to about 75 degrees with respect to the lengthwise axis of the fluid applicator. The fluid applicator can define a second face intersecting the first face. The coating apparatus can further include a rotation mechanism and an axial motion mechanism. Other embodiments are also included herein.

An extendable roller paint applicator device for extending the roller to inaccessible surfaces includes a hand grip. The hand grip has a painting surface and an extension surface. A stem is positioned upon the painting surface of the hand grip. The stem has a distal end and a proximal end relative to the hand grip. Furthermore, the distal end of the stem has a bend. A roller enwraps the bend of the stem and is coupled to the bend of the stem by a pivot. The pivot rotates the roller when pushed against a surface. A brush is positioned around the roller. Additionally, an extender is positioned upon the extension surface of the hand grip. The extender increases a length of the hand grip relative to the roller.

A coating applicator that applies a coating or liquid to a variety of different substrates having different contoured surfaces is disclosed. A coating applicator of the present disclosure is able to reach, contact, and cover the entirety of a contoured substrate. In this manner, the coating applicator is able to transfer a coating to the entirety of the contoured substrate. Additionally, fluid application systems of the present disclosure include systems for advantageously providing a fluid to a fluid applicator.

A rotatable tool assembly including a motor and a tool assembly operatively coupled to the motor. The tool assembly includes an epicyclic gear system rotatably coupled to the motor and one or more tools rotatably coupled to the epicyclic gear system. The motor is configured to rotate the epicyclic gear system, and the epicyclic gear system is configured to rotate the tool.

An extension paint spray-roller system includes a hydraulic paint spray extension system to which is mounted a paint roller system for use in combination. The hydraulic paint spray extension system includes an on-off control valve/handle communicating with a source of high pressure paint and connected via a straight-through swivel joint to a pole extension having a spray tip mounted at the oppositive end. A paint roller system is mounted to the paint spray extension system by a mounting system which permits a commercially available off-the-shelf paint roller to be utilized with the system.

A paint dispensing roller assembly that comprises an applicator member of an absorbent material defining an enclosed applicator member cavity. The assembly further comprises a paint dispensing member disposed at least partially within the enclosed applicator member cavity and having an outer undulating surface with an alternating plurality of ridges and valleys defining an enclosed paint mixing cavity having at least one enclosed aperture defined thereon. The paint dispensing roller assembly also includes a cantilevered mixing member disposed at least partially within the enclosed paint mixing cavity and having at least one flange projecting radially from the cantilevered mixing member. The paint dispensing roller assembly further comprises a roller body including a handle and a shell portion defining a shell cavity wherein the applicator member is partially disposed. The applicator member and paint dispensing member are operably configured to rotate 360 degrees with respect to the roller body.

A roller spreading device for spreading a butter substance over a food product is provided. The device includes a basin structure and a roller member. The basin structure is sized to hold the butter substance for melting therein, the basin structure including a lower floor surface extending with an arcuate structure. The roller member includes a cylindrical outer surface with multiple recesses therein sized to capture the butter substance along the multiple recesses. The roller member, suspended within the basin structure, rotates about an axis such that the roller member rotates through the butter substance pooled along the arcuate structure.

A paint roller pressure adjusting device to connect to a pole at a first end and a paint roller at a second end, the paint roller pressure adjusting device including a pressure adjusting portion, including a base disposed at a first end of the pressure adjusting portion, a top portion disposed at a second end of the pressure adjusting portion, the top portion having a threaded paint roller connecting portion disposed at a top surface of the top portion to connect to the paint roller, and a spring disposed between the base and the top portion, and a regulating portion, including a main body to be inserted into through the base and the spring of the pressure adjusting portion, and a threaded portion to correspond to the spring such that the main body screws into the spring.

In an embodiment, a paint roller manufacturing system and method uses a fabric-coating applicator to apply a fabric adhesive onto a portion of a perforated paint roller cover fabric material having a plurality of perforations through which adhesive may flow, and into the plurality of perforations and into interstitial spaces of the fabric material, to yield a length of coated fabric. An inner strip and an outer strip are wound about a mandrel in offset relation. A strip-coating applicator is used to apply a strip adhesive to the outer strip as it is wound about the mandrel. Simultaneously with the step of applying the strip adhesive to the outer strip, a portion of the coated paint roller fabric material is received at the outer strip and the length of coated fabric is wound about at least the outer strip to form a paint roller tube.
