Abstract

An exclusive molding method for producing cloth-based parts of loudspeaker is employed to move a resin-dipped and dried cloth roll to pass intermittently through a heating device and a mold set in order, so that the cloth roll is preheated then molded into shape of parts and cut into the desired parts with a heightened working efficiency.

Claims

exact text as granted — not AI-modified
1 . An exclusive molding method for producing cloth-based parts of loudspeaker, comprising: 
 (a) Providing a resin-dipped and dried cloth roll;    (b) Moving the cloth roll to pass through a heating device and a mold set intermittently in order, such that the cloth roll is preheated by the heating device then molded to show the shape of parts; and    (c) Cutting the molded cloth into pieces to obtain the desired cloth-base parts.    
   
   
       2 . The exclusive molding method according to  claim 1 , in which, after passing through the heating device, the cloth roll is leveled by a leveling device before been moved to the mold set.  
   
   
       3 . The exclusive molding method according to  claim 2 , the leveling device comprises at least of a pair of rollers for pinching and flushing the cloth roll.  
   
   
       4 . The exclusive molding method according to  claim 1  or  claim 2 , in which the preheating temperature provided by the heating device is in the range of 150° C.˜200° C.  
   
   
       5 . The exclusive molding method according to  claim 1  or  claim 2 , in which the preheating time is in the range of  10 ˜ 15  seconds.  
   
   
       6 . The exclusive molding method according to  claim 1  or  claim 2 , in which cloth-based parts are formed by the mold set under room temperature.
