Abstract
An adhesive layer is provided on a base material in the shape of an elongated film, powder particles are adhered thereon, and then other powder particles and media vibrated in a container are contacted with this adhesive layer. Next, the powder particles are embedded on the surface of the adhesive layer as a monolayer in which part of the powder particle protrudes, so as to form a laminate, and excess powder particles adhered to the laminate are removed. Therefore, a monolayer powder film, consisting of many powder particles embedded as a monolayer so that part thereof protrudes, is produced.
Claims12
A production method for a monolayer powder film on a base material in a shape of an elongated film, consisting of plural powder particles embedded on the surface of an adhesive layer provided on a base material in the shape of an elongated film as a monolayer, so that part of said powder particle protrudes, comprising, in a continuous process of feeding the base material in the shape of an elongated film from an unwinding device to a winding device:
- forming said adhesive layer on at least one surface of said base material;
- adhering said powder particles to said adhesive layer so as to form a laminate;
- embedding said powder particles on the surface of said adhesive layer as a monolayer, so that part of said powder particle protrudes, by contacting said adhesive layer with other powder particles and media vibrated in a container;
- and
- removing excess powder particles adhered to said laminate.
