Production of disposable garments

Abstract

The present invention relates to method for manufacturing disposable upper body garments having sleeves and a front portion. The method comprises feeding a main film in a longitudinal direction and forming an assembly comprising a first sleeve film and a second sleeve film arranged on an upper surface of the main film. The method further comprises, for a first one of the garments, welding the first sleeve film to the main film along an outline defining the sleeves of said first one of the garments, and for a second one of the garments, welding the second sleeve film to the main film along an outline defining the sleeves of said second one of the garments. After the welding steps, the method comprises punching through the assembly to define a neck opening of the first one and the second one of the garments; and punching through the assembly along an outline of the first one and the second one of the garments.

1 . A method for manufacturing disposable upper body garments having sleeves and a front portion, comprising:
 feeding a main film in a longitudinal direction, the film having a first and a second transversely opposing longitudinal edge portion separated by a centre line extending in the longitudinal direction;   forming an assembly comprising a first sleeve film and a second sleeve film arranged on an upper surface of the main film, wherein the first sleeve film is formed by folding the first edge portion of the main film onto the upper surface of the main film, and wherein the second sleeve film is formed by folding the second edge portion of the main film onto the upper surface of the main film;   for a first one of the garments, welding the first sleeve film to the main film along an outline defining the sleeves of said first one of the garments,   for a second one of the garments, welding the second sleeve film to the main film along an outline defining the sleeves of said second one of the garments;   punching through the assembly to define a neck opening of the first one and the second one of the garments; and   punching through the assembly along an outline of the first one and the second one of the garments.   
     
     
         2 . The method according to  claim 1 , comprising:
 welding the first/second sleeve film to the main film to form an underarm seam;   punching through the first/second sleeve film and the main film to define the sleeve opening and the front portion.   
     
     
         3 . The method according to  claim 1 , comprising:
 welding the first/second sleeve films to the main film to form an underarm seam and a shoulder to arm seam;   punching through the first/second sleeve film and the main film to define the sleeve opening and the front portion   
     
     
         4 . The method according to  claim 1 ,
 wherein the first one and the second one of the garments are arranged adjacent to each other along the longitudinal direction.   
     
     
         5 . The method according to  claim 1 , further comprising removing a remaining portion of the assembly arranged between the first and second ones of the garments 
     
     
         6 . The method according to  claim 1 , further comprising separating the first and second ones of the garments from each other. 
     
     
         7 . The method according to  claim 1 , further comprising:
 folding the assembly along the longitudinal direction; and   rolling the folded assembly into a roll.   
     
     
         8 . A disposable upper body garment manufactured by the method according to  claim 1 . 
     
     
         9 . A system for manufacturing of disposable upper body garments having sleeves and a front portion, comprising
 a feeding mechanism for feeding a main film in a longitudinal direction, the film having a first and a second transversely opposing longitudinal edge portion separated by a centre line extending in the longitudinal direction;   an assembling mechanism configured to arrange a first sleeve film and a second sleeve film on an upper surface of the main film by folding the first and second edge portions onto the upper surface to form the first sleeve film and the second sleeve film, respectively;   a welding tool configured to weld the first sleeve film to the main film along an outline defining the sleeves of a first one of the garments and to weld the second sleeve film to the main film along an outline defining the sleeves of a second one of the garments;   a cutting tool configured to cut out a neck opening of the first one and the second one of the garments; and   a punching tool configured to punch through the assembly along an outline of the first one and the second one of the garments.   
     
     
         10 . The system according to  claim 9 , wherein the welding tool comprises a rotatable cylinder. 
     
     
         11 . The system according to  claim 10 , further comprising a finishing mechanism for folding and rolling the assembly 
     
     
         12 . The system according to  claim 9 , further comprising a finishing mechanism for folding and rolling the assembly.
