<p>A sewing machine for a non-woven fibre fleece has a multi-part machine frame (1) consisting of a top (2) and bottom (3) parts that together support aggregate units (9.1, 9.2) one of which (9.1) has an oscillating multi-needle beam (6). The second aggregate unit (9.2) has a fleece support bench (10) with a number of top-mounted columns (4.1, 4.2) that maintain separation between the lower and upper frames (2), and end-supports (14.1, 14.2) at opposite ends of the under the upper frame (3). The sewing machine further has semi-elastic stud bolts (12) for oscillating loads at each side that hold the upper and lower frames and their aggregates in a single unit.</p> |
