Adhesive bandage pad module and method for making and applying adhesive bandage pads to a web
View Patent ↗An adhesive bandage pad module, and a method of making adhesive bandage pads, are disclosed. The adhesive bandage pad module, and method of making an adhesive bandage pad, include a servo motor which rotates a knife roll, a transfer roll, and an infeed assembly, a continuous pad strip fed to the infeed assembly, a knife roll and a blade that cuts the continuous pad strip against an anvil, that tangentially contacts the knife roll, on the knife roll. In the module, the amount of pressure exerted by the blade upon the anvil, and transferring of the cut pad onto an adhesive backing on the transfer roll are controlled.
1. A method of making and applying a bandage pad to a bandage web to form and adhesive bandage, comprising:
rotating at least one servo motor, wherein said at least one servo motor rotates a knife roll having a plurality of blades thereon, a transfer roll, and an infeed assembly;
feeding a continuous pad strip to the infeed assembly,
cutting the continuous pad strip against an anvil with a blade located on the knife roll, said cutting forming individual bandage pads;
carrying a cut pad to said transfer roll, said transfer roll being in contact with said knife roll;
synchronizing the transfer of individual bandage pads from said knife roll to said transfer roll; and
transferring the cut pad into an adhesive backing.
2. The method of claim 1 , further comprising controlling an amount of pressure exerted by the blade upon the anvil during said cutting.
3. A method of making an adhesive bandage comprising an adhesive backing and a pad, comprising:
feeding a continuous pad strip to an infeed assembly;
rotating at least one motor, which at least one motor rotates a knife roll, a transfer roll, and the infeed assembly;
cutting the continuous pad strip against an anvil with a blade located on the knife roll;
controlling an amount of pressure exerted by the blade upon the anvil during said cutting;
carrying a cut pad to said transfer roll, said transfer roll being in contact with said knife roll; and
transferring the cut pad onto an adhesive backing;
wherein controlling an amount of pressure is accomplished using a force adjuster, said force adjuster comprising an adjuster, a pressure plate connected to said adjuster, wherein said pressure plate is forced by said adjuster in a direction toward said anvil, and at least two bearings, said bearings responding to a movement of said pressure plate by exciting a force on said anvil in the same direction as the movement of said pressure plate.
4. The method of claim 2 , wherein controlling an amount of pressure is accomplished using a force adjuster, said force adjuster comprising an adjuster, a pressure plate connected to said adjuster, wherein said pressure plate is forced by said adjuster in a direction toward said anvil, and at least two bearings, said bearings responding to a movement of said pressure plate by exerting a force on said anvil in the same direction as the movement of said pressure plate.
