Title: Tufted carpet tile
Inventor: YAMAGUCHI ATSUSHI
IPC: B32B5/16
Filed: 1990-08-23
Abstract: PURPOSE:To obtain an effective non-oriented pile by making a primary base cloth of the structural body in which a fiber-like web laminated body is stuck together with cotton or silk, and thereto by planting nylon pile and by subjecting the rear surface thereof to backing treatment with resins. CONSTITUTION:The fibers constituting a fiberlike web laminated body 3 are inorganic fiber such as glass fiber, natural fiber such as cotton, synthetic resins such as polyester nylon. After having been laminated as a web by carding, these are subjected to needle-punching to make a laminated body. Or, webs are laminated on a fabric or nonwoven fabric 2 and are stuck together by needle-punching to make a laminated body. The most important point is the thickness of the fiberlike web laminated body, and this is made to be greater than 2.5mm and less than 4.0mm. Thus, manufactured tufted carpet tiles have little orientation in their cut piles, and are easy in working and in color and pattern adjustment, and the occurrence of pile deformation and shading after use is very rare.

In such a case, since the idler gear 5a which is driven in a high speed. In such a case, since the idler gear 5a approaches from the outside of the flywheel 3a along its drive direction, no strong force is applied and the force of the spring 9a is comparatively weak.
