System for automatically rippling and hackling wig yarns

A system for automatically rippling and hackling wig yarns while the yarns are fed in one direction therethrough comprising:

• means for heating and rippling the wig yarns, said means comprising a pair of rollers engaging with each other such that said wave rollers heat and ripple the wig yarns, each of said rollers having an outer surface and a heating coil means for heating said outer surface to a temperature of between 80.degree.-200.degree. C., said outer surface having a plurality of rounded teeth extending axially thereacross, the rounded teeth of the roller surface having a pitch of between 1 mm to 30 mm and a tooth height of between 1 mm to 30 mm;
• a cooler arranged after said heating and rippling means and comprising a cooling belt and pneumatic means, said pneumatic means for directing cooling air toward said cooling belt, said pneumatic means comprising a fan, a pipe communicating with said fan, and a diffuser connected to said pipe distal said fan, said diffuser directed toward said cooling belt;
• means for hackling the wig yarns positioned after said cooler, said means for hackling comprising a plurality of hackling conveyors, each of said hackling conveyors including a pair of belt pulleys and an endless hackle belt wrapping about said belt pulleys, said hackle belt having a plurality of erect hackle pins extending outwardly therefrom, said hackle belt moving in a direction opposite to the feeding direction of the wig yarns;
• a pair of tension rollers arranged between said cooler and said hackling means, said tension rollers receiving the wig yarns therebetween;
• and
• means for pulling said wig yarns from said hackling means, said pulling means comprising a plurality of pulling rollers, at least one of said plurality of pulling rollers having a different diameter than another of said plurality of pulling rollers.

• means for hackling the wig yarns positioned after said cooler, said means for hackling comprising:
• a plurality of hackling units, each including a hackling bar and drive means for driving said hackling bar, said hackle bar having a plate provided with a plurality of erect hackle pins extending outwardly therefrom, said hackle bar vertically reciprocating by a rotational force of said drive means, said drive means comprising a motor and a power transmission gear for transmitting the rotational force of said motor to said hackle bar;
• and
• a plurality of hackling conveyors, each of said hackling conveyors having a pair of belt pulleys and an endless hackle belt wrapping about said belt pulleys, said hackle belt having a plurality of erect hackle pins extending outwardly therefrom, said hackle belt moving in a direction opposite to the feed direction of the wig yarns;
