Securing and pressuring system for drafting rollers for automated textile drafting system

A textile drafting apparatus adapted for securing and urging together at least one pair of drafting rollers used in drafting a strand of textile material passing therebetween, said apparatus comprising:

• (a) a first frame supporting and maintaining a first roller of said at least one pair of drafting rollers in a substantially fixed position allowing rotational movement thereof;
• (b) a second frame supporting a second roller of said at least one pair of drafting rollers and movably cooperating with said first frame such that said first and second rollers are substantially parallel and can cooperatively draft a strand of textile material passing therebetween when said rollers are in an operative drafting position, and wherein an upper portion of said second frame including said second roller is slidably removable from a bottom portion of said second frame;
• and
• (c) pneumatic adjustment means connected to said second frame for selectively moving said second frame along a direction toward and away from said first frame whereby said second roller can be moved toward and into operative engagement and away and into inoperative engagement with said first roller.

• and
• (c) pneumatic adjustment means connected to said second frame for selectively moving said second frame along a direction toward and away from said first frame whereby said second roller can be moved toward and into operative engagement and away and into inoperative engagement with said first roller, and wherein said first roller is a lower roller and said second roller is an upper roller and wherein said pneumatic adjustment means provides only vertical movement of said second frame and roller toward and away from said first frame and roller.

• (b) a second frame supporting a second roller of said at least one pair of drafting rollers, and wherein an upper portion of said second frame including said second roller is removable by slidable movement thereof in a horizontal direction substantially perpendicular to said vertical direction;
• and
• (c) pneumatic adjustment means for selectively vertically moving said second frame between an inoperative extended position wherein said first and second rollers are spaced-apart and an operative retracted position wherein said first and second rollers are urged cooperatively together to facilitate drafting of a strand of textile material passing therebetween.
