| 摘要 | A method of manufacturing hairpieces which allows them to be rapidly produced but provides a product that is durable, easy to care for and natural in appearance. Hairs are temporarily positioned with a holding means, a base material is positioned around the hairs to permanently secure them in place and the holding means for temporarily positioning the hairs is removed. | ||||||
| 权利要求 | 2. A process as in claim 1, wherein the holding material is sodium thiosulfate. 3. A process as in claim 1, wherein the elastomeric block and hairs are placed in a curing pan before the holding material is spread over the block and around the hairs projecting from the block. 4. A process as in claim 1, wherein the backing member is rubber, spread, while in liquid form, against the holding mass before the holding mass is removed and around the ends of the hairs removed from the elastomeric block and thereafter cured to a solid form. 5. A process as in claim 4, wherein the rubber is cured under pressure, whereby the ends of the hairs are more tightly embedded therein. 6. A process as in claim 5, further including the step of cutting away excess backing material from the hairs to obtain a desired hairpiece configuration. 7. A method of making a hairpiece comprising temporarily securing hairs in a desired pattern with a temporary holding means by inserting the ends thereof into an elastomeric block in a desired pattern and by thereafter flowing a holding mass in liquid form around the hairs, solidifying the holding mass and removing the holding mass and the hairs from the elastomeric block. placing a base material around the hairs to permanently secure them in the desired pattern; and removing the temporary holding means. 8. The method of making a hairpiece, as in claim 7, wherein the base material is placed around the ends of the hair that have been withdrawn from the elastomeric block. |
