Abstract
Method of forming a rubber latex glove having a textured interior surface and a textured exterior surface, one of the textured surfaces being transfer textured and the other textured surface being formed by impact spray on a molded rubber latex film with liquid rubber latex droplets while the film is in uncured condition.
Claims24
The method of forming a roughened surface glove comprising dip-forming and partially air-drying a coating of aqueous solution of rubber latex while in contiguous film-covering relation on a desired use portion of a hand-shaped glove form having fingers and a thumb, to form an uncured film of rubber latex on said form with an inner surface having a mirror image of the film-covered portion of the outer surface of the form,
- externally spraying an aqueous liquid latex solution in droplet form onto the outer surface of said film in the palm, finger and thumb-gripping zones formed thereby, and while said film is in an uncured condition, to thereby form a rough external surface on said film,
- and curing and removing the resulting latex-droplet-impacted glove film including the impacted latex droplet solution thereon, from said form,
- said external spraying being effected by simultaneously directing a spray of said liquid latex soltuion from two sources and in two intersecting path directions of latex spray toward the palm side of said form while effecting relative motion between said form and said spray sources to effect relative effective rectilinear movement of said form along a path extending toward, in front of and laterally past and away from said two spray sources of liquid latex solution while thereby varying the effective zones of intersection and angles of intersection of the spray from said two sources with said uncured film as a function of said rectilinear motion of said form toward, past and away from said spray.
A method of forming a glove provided with a roughened surface area which comprises:
- dip-forming and partially air-drying a layer of an aqueous solution of rubber latex on the surface of a hand-shaped glove form having palm, thumb and fingers forming surfaces, to form an uncured latex film thereon,
- externally spraying an aqueous liquid latex solution in minute droplet form along two intersecting latex spray pattern paths from two simultaneous effectively different source zones from which the respective general spray pattern paths of latex spray droplets are simultaneously angularly differently directed relative to one another onto the outer surface of said film in the palm, finger and thumb-gripping zones formed thereby, by impacting such outer surfaces with the spray droplets to form impact craters in said film while said film is in an uncured condition on its air-exposed surface to thereby form a roughened impact cratered surface on said film,
- discontinuing said spraying when the desired impact-roughened areas are produced,
- and curing the resulting latex-droplet-impacted glove film, including the impacted latex droplet solution thereon, on said form, and removing the cured film from said form.
