Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mat disassembling treatment method and apparatus for separating and disassembling a mat having a spring body therein, for example, a mat used for a bed or the like, into a cloth portion (including leather material) and a spring body. It is about.

[0002]

2. Description of the Related Art Conventionally, when a mat having a built-in spring body therein, for example, a bed or the like is separated and disassembled into a cloth portion and a spring body, an operator cuts the cloth portion with a knife or the like.
By peeling this off from the spring body, the fabric part and the spring body were separated and disassembled.
