Method for producing bandages
In a method for producing bandages such as support bandages for knee and elbow joints, an elastic fabric material layer is provided on which reinforcement elements are placed and an uncured elastomer is applied to the fabric material in several layers or sprayed onto the fabric material layer so as to completely cover and embed the reinforcement elements which are firmly engaged thereby with the fabric material layer and form three-dimensional stabilizing structures projecting from the surface of the fabric material layer.
1. A method for producing bandages ( 1 ) for knee and elbow joints, comprising the steps of: providing an elastic fabric material layer ( 2 ), placing reinforcement elements ( 5 , 6 ) in predetermined positions onto one side of the elastic fabric material layer ( 2 ), covering the elastic fabric material layer with the reinforcement elements ( 5 , 6 ) disposed thereon with several layers of elastomer coatings by spraying a first uncured elastomer coating in a liquid or gooey state onto the elastic fabric material layer ( 2 ) so as to embed the reinforcement elements ( 5 , 6 ) disposed on the elastic fabric material layer ( 2 ), while penetrating into the elastic fabric material layer ( 2 ) each additional coating being applied to a previously applied layer when the previously applied coating is only partially cured and fully curing the elastomer coatings embedding the reinforcement elements ( 5 , 6 ) to firmly engage the reinforcement elements ( 5 , 6 ) with the elastic fabric material layer ( 2 ) and forming three-dimensional molded areas ( 3 , 4 ) projecting from the one side of the fabric material layer ( 2 ).
2. The method according to claim 1 , wherein, after the elastomer coatings are sprayed onto the elastic fabric material layer ( 2 ), a flock coating is applied to the elastomer material.
3. The method according to claim 2 , wherein the flock coating is applied before the last sprayed-on elastomer coating is fully cured.
4. The method according to claim 1 , wherein the elastomer coatings are silicone material coatings.
5. The method according to claim 1 , wherein the elastomer coatings are applied in spaced relationship from opposite end edges of the fabric material layer ( 2 ).
6. The method according to claim 1 , wherein the elastomer coatings are applied to the fabric material layer without additional cement.
7. A method according to claim 1 , wherein the reinforcement elements ( 5 , 6 ) comprise spaced rod-shaped elements ( 6 ) with annular element ( 5 ) disposed between the spaced rod-shaped reinforcement elements.
8. A method according to claim 7 , wherein the rod-shaped reinforcement elements ( 6 ) are metal spring elements and the annular reinforcement elements ( 5 ) are formed of an elastically resilient material.
9. A method for producing bandages for knee and elbow joints, comprising the steps of: providing an elastic fabric material layer ( 2 ), placing straight reinforcement elements ( 5 ) on opposite sides of an annular reinforcement element ( 6 ) in spaced relationship in predetermined positions onto the elastic fabric material layer ( 2 ), applying successively uncured elastomer material in several layers to the elastic fabric material so as to cover the reinforcement elements ( 5 , 6 ) so that the elastomer material at least partially penetrates the fabric material layer ( 2 ), and curing the elastomer, material thereby firmly engaging the reinforcement elements ( 5 , 6 ) with the fabric material layer thereby forming three-dimensional molded areas ( 3 , 4 ) projecting from the surface of the fabric material layer ( 2 ).
