专利汇可以提供Conversion apparatus for textile fibers专利检索，专利查询，专利分析的服务。并且An apparatus for converting a mass of textile filaments in the form of textile material waste, tangled thread waste or colddrawable continuous filaments of a synthetic polymer to a useful product comprising a forwarding means for slow feeding the filaments under a restrained condition to a rotatable substantially cylindrical open structure having a multiplicity of outwardly projecting filament-engaging needles mounted around the periphery of the structure and a number of combs having outwardly projecting teeth mounted around the periphery and spanning the structure.，下面是Conversion apparatus for textile fibers专利的具体信息内容。
1. In a machine for converting textile waste to threaded form, and from threaded form to fibers, a substantially cylindrical fabric reducing assembly, feed means for feeding said waste to said assembly and associated drive means, said assembly comprising, in combination, (i) journalled mounting means, (ii) a rotatable and open supporting structure having a circular perimeter radially connected to said mounting means, (iii) a plurality of textile-opening and thread-shredding staves around said perimeter, spanning said supporting structure, said staves each having mounted thereon at least two staggered rows of outwardly projecting, fabric-opening needles, and (iv) a comb on at least one edge of each of said staves, said comb consisting essentially of a set of outwardly projecting, thread-shredding teeth, said feed means including wire covered feed rolls, said drive means being coupled to said wire covered rolls and to said open supporting structure for their rotation at respectively low and high speeds, said wire covered rolls being situated adjacent the perimeter of said reducing assembly for holding said waste tightly to release it slowly toward said reducing assembly against the relatively high-speed pull of said needles and combs.
2. The invention according to claim 1 in which said needles incline in the direction of rotation of said supporting structure, said combs are radially disposed on the leading edges of the staves and said needles project radially outwardly beyond said combs.
3. The invention according to claim 2 in which (i) said assembly is provided with a casing, said casing being substantially volute and embracing at least the upper perimeter of said reducing assembly and being slightly spaced therefrom, (ii) said casing being spaced from said mounting means to permit the admission of air through said open supporting structure, and (iii) said supporting structure being in the form of a pair of circular end plates, having air admitting openings therein, intermediate plates at intervals between said end-plates, and rim-bands around the perimeter of said plates, said staves spanning said rim-bands, said casing having a volute discharge exit beneath said journalled mounting means.
4. A machine for converting a mass of textile filaments selected from the group consisting of: textile material waste, tangled thread waste and cold-drawable continuous filaments of a synthetic polymer to a useful product, said machine comprising: a forwarding means adapted to advance said mass of textile filaments at a low speed under a restrained condition, a substantially cylindrical conversion assembly adjacent to said forwarding means having journalled mounting means, rotatable and open supporting structure with a circular periphery radially connected to said mounting means, a multiplicity of outwardly projecting filament-engaging needles mounted in groups of staggered rows around said periphery and at least one comb spanning said supporting structure adjacent each group of needles, said combs consisting essentially of a set of outwardly projecting teeth, drive means couPled to said supporting structure for its rotation at a very high surface speed relative to the speed at which said mass of textile filaments is forwarded thereto, and a casing substantially enclosing said conversion assembly, the high speed rotation of said conversion assembly creating a flow of air through said casing, said casing presenting an air-intake opening in the region between said forwarding means and said conversion assembly and having a volute discharge exit for converted fibers beneath said journalled mounting means, said forwarding means including wire covered feed rolls closely adjacent the periphery of said conversion assembly for holding said filaments tightly and releasing them slowly toward said conversion assembly against the high speed pull of said needles and combs.
5. The invention according to claim 4 in which said supporting structure has a set of staves around said periphery spanning said supporting structure, each stave mounting one group of outwardly projecting fabric-opening needles and a comb on at least one edge thereof.
6. The machine according to claim 4 in which a means for heating said mass of textile filaments is provided in said forwarding means.
