Abstract

Abstract A method and apparatus for applying flock to a substrate, such as a garment, comprising a compact, portable, self-contained flocking machine in which the cabinet and flocking trays are non-metallic and are preferably wood and plastic, respectively, whereby the electric field from an electrode in the flocking tray to the metallic garment holding platen causes the flock to move in a straight, uniform, dense pattern from the flock tray to the garment. In addition, the high voltage electrode in the flock tray is not energized until the flock tray has moved up and made contact with the garment holding platen to prevent flock from coming up out of the tray while the tray is moving up and down and to prevent any risk of shock to the operator. The platen is mounted on a rotatable shaft and diametrically opposed to a similar platen in an uppermost position which is operatively associated with a screen printer. In use, a printed substrate is flocked while an additional substrate is being printed.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 158 words
A method for flocking a substrate comprising: (a) providing a flocking apparatus including a cabinet, a substrate holding turret with a horizontal rotatable shaft having two substrate holding metal platens diametrically opposed thereon, a screen printing apparatus located above the turret, a flocking tray located below the turret, and detent means on the turret apparatus for registering one platen with the screen printing apparatus for printing an adhesive onto the substrate associated therewith and the other platen with the flocking apparatus, (b) positioning a high voltage metallic electrode in said flocking tray, (d) establishing an electric field between said electrode and the platen associated therewith, (c) and forming said cabinet and flocking tray of non-metallic materials, whereby the flock will move in a parallel, dense, straight and uniform direction from said flock tray to a printed substrate on the lowermost platen when said electric field is established and while a substrate on the uppermost platen is being printed.
Claim 2
Independent Claim 158 words
A method for flocking a substrate comprising: (a) providing a flocking apparatus including a cabinet, a substrate holding turret with a horizontal rotatable shaft having two substrate holding metal platens diametrically opposed thereon, a screen printing apparatus located above the turret, a flocking tray located below the turret, and detent means on the turret apparatus for registering one platen with the screen printing apparatus for printing an adhesive onto the substrate associated therewith and the other platen with the flocking apparatus, (b) positioning a high voltage metallic electrode in said flocking tray, (d) establishing an electric field between said electrode and the platen associated therewith, (c) and forming said cabinet and flocking tray of non-metallic materials, whereby the flock will move in a parallel, dense, straight and uniform direction from said flock tray to a printed substrate on the lowermost platen when said electric field is established and while a substrate on the uppermost platen is being printed.
Claim 3
Dependent Claim 51 words
The method according to claim 1 including the steps of moving said flocking tray up into contact with the lowermost platen for flocking and then moving said tray back down, and energizing said electrode in said flocking tray only after said flocking tray has moved up and contacted said lowermost platen.
Claim 4
Dependent Claim 19 words
The method according to claim 1 including grounding all metal in the cabinet except for said high voltage electrode.
Claim 5
Dependent Claim 14 words
The method according to claim 1 wherein said flocking step comprises flocking a garment.
