Abstract
A method for making individual contoured wound dressings comprising: providing a supply of a thin release web (40); and protective release covering (32); removably attaching and contouring a substantially continuous strip of an adhesive material (26) between said thin release web (40) and protective release covering (32) forming a first laminate (46); transporting said first laminate (46) to a delaminating station (54) where-at said thin release web (40) is peeled from said first laminate (46); supplying an adhesive carrier (28); merging and laminating said adhesive carrier (28) to the exposed adhesive layer forming a second laminate (64); and transporting said second laminate (64) to and through a cutting Station (68) to be cut into individual wound dressings or bandages.
Claims14
A method for making discrete and individual wound dressings having a contoured skin-friendly and moisture activated adhesive layer, said method including the following steps;
- (a) providing a substantially continuous supply of a thin release web of material;
- (b) providing a substantially continuous supply of a thin protective release covering;
- (c) providing a substantially continuous strip of an adhesive material, said strip of adhesive having predetermined thickness and malleable properties;
- (d) removably attaching said strip of adhesive material to and between said thin release web and said protective release covering while simultaneously contouring said adhesive material to a predetermined shape by merging and carrying a first laminate of said adhesive material, thin release web and said protective release covering through a calibration and contouring station;
- (e) exposing a major surface of said contoured adhesive material by removing said thin release web from said contoured adhesive material by carrying said first laminate to and through a subsequent delaminating station;
- (f) providing a substantially continuous web of an adhesive carrier material;
- (g) merging said adhesive carrier layer with said contoured adhesive layer to form a second laminate by applying said adhesive carrier layer to fully cover said exposed major surface of said adhesive layer while simultaneously applying pressure to said second laminate by carrying said second laminate to and through a laminating station;
- and
- (h) cutting said second laminate into predetermined discrete sized and contoured individual wound dressings by carrying said second laminate to and through a cutting station in a predetermined registered and timed relationship.
A method for making discrete and individual wound dressings having a contoured skin-friendly and moisture activated adhesive layer, said method including the following steps:
- (a) providing a substantially continuous supply of a thin release web of material;
- (b) providing a substantially continuous supply of a thin protective release covering;
- (c) providing a substantially continuous strip of an adhesive material, said strip of adhesive having predetermined thickness and malleable properties;
- (d) removably attaching said strip of adhesive material to and between said thin release web and said protective release covering while simultaneously contouring said adhesive material to a predetermined shape by merging and carrying a first laminate of said adhesive material, thin release web and said protective release covering through a calibration and contouring station;
- (e) exposing a major surface of said contoured adhesive material by removing said thin release web from said contoured adhesive material by carrying said first laminate to and through a subsequent delaminating station;
- (f) providing a substantially continuous web of an adhesive carrier material;
- (g) merging said adhesive carrier layer with said contoured adhesive layer to form a second laminate by applying said adhesive carrier layer to cover said exposed major surface of said adhesive layer at a merging station;
- (h) removing substantially any and all gas pockets interior of said second laminate by carrying said second laminate through a air removing station;
- (i) applying pressure to said second laminate by carrying said second laminate to and through a laminating station;
- and
- (j) cutting said second laminate into predetermined discrete sized and contoured individual wound dressings by carrying said second laminate to and through a cutting station in a predetermined registered and timed relationship.
