Drafting equipment, has compression device including suction shoe and compressive strip tile, which perforates and winds around upper output roller, where shoe faces middle roller pair

摘要

The equipment (1) has a compression device, and a main drafting zone with lower and upper output rollers (5, 6). The compression device includes a suction shoe (8) and a compressive strip tile (7) perforating and winding around the roller (6). The suction shoe faces a middle roller pair (3). Compression effect of the compression device unfolds the shoe in the main drafting zone between the middle roller pair and the output roller pair.
