Abstract
A method and apparatus for automatically splicing two continuous three-layer tapes, wherein a longitudinally movable continuous wound tape is transversely cut so as to form individual wound pads which are applied in longitudinally spaced positions on adhesive surfaces of continuous carrier foils, and wherein a splicing element is cut from the continuous wound tape and is applied on tail and head portions of two continuous carrier foils.
Claims13
A method for manufacturing plasters including automatically splicing two continuous three-layer tapes, the method comprising:
- providing two longitudinally movable continuous three-layer tapes, each including a continuous carrier foil having an adhesive surface, a top protective film applied on the adhesive surface of the continuous carrier foil and a back protective film applied on a surface of the carrier foil opposite the adhesive surface,
- applying a top adhesive splicing element on tail and head portions of the top protective films and a back adhesive splicing element on tail and head portions of the back protective films,
- delaminating the top protective films to expose the adhesive surfaces of the two continuous carrier foils,
- providing a longitudinally movable continuous plaster wound tape, transversely cutting said continuous plaster wound tape to form individual wound pads and applying said wound pads in longitudinally spaced positions on the adhesive surfaces of the continuous carrier foils, and
- cutting from said continuous plaster wound tape a plaster splicing element and applying said plaster splicing element on the adhesive surfaces of the two continuous carrier foils on tail and head portions of the continuous carrier foils.
An apparatus for manufacturing plasters including automatically splicing two continuous three-layer tapes, the apparatus comprising:
- an unwinding unit configured for unwinding from respective reels two longitudinally moving three-layer tapes, each including a continuous carrier foil having an adhesive surface, a top protective film applied on the adhesive surface of the continuous carrier foil and a back protective film applied on a surface of the continuous carrier foil opposite the adhesive surface,
- a splicing unit configured for applying a top adhesive splicing element on tail and head portions of the top protective films and a back adhesive splicing element on tail and head portions of the back protective films,
- a first delamination unit configured for removing the top protective films to expose the adhesive surfaces of the continuous carrier foils,
- a second unwinding unit configured for unwinding from a reel a longitudinally moving continuous plaster wound tape,
- a cut-and-slip unit configured for transversely cutting said continuous plaster wound tape to form individual plaster wound pads and for applying said plaster wound pads in longitudinally spaced positions on the adhesive surfaces of the continuous carrier foils,
- wherein said cut-and-slip unit is also configured for cutting from said continuous plaster wound tape a plaster splicing element and for applying said plaster splicing element on the adhesive surfaces of the two continuous carrier foils on tail and head portions of the continuous carrier foils.
