Free Spiral Brushes - Spirali libere |
|
| | 
| | The spiral brush is made of a spiral strip with a defined inner diameter which can be supplied and assembled on a body properly fixed, or as spare part to be assembled by the customer. The coils of the spiral brush may be wound up closed to or distanced. The fill density of the brushing surface or thickness may be compared to the winding pitch or to the number of coils wound onto a body. |  | ELECTRIC-WELDED SPIRAL BRUSHES: spiral brushes wound up closed, welded at their inside in order to realize a single cylindrical module.
Thus it is possible to assembly more modules in order to obtain the length requested; moreover modules become easily interchangeable. Available with different diameters, filaments and trim length. BALANCING: it can be recommended dynamic balancing for all brushes mounted onto an arbor and get exploited at high rotating speed. SIT can realize the dynamic balancing and issue the relative certificate

| 
| | 1) high density (closed coils) 2) medium, 3) low | 
| Material will be moved according to sense of rotation of the brush
and kind of winding of the spiral brush:
A= left handed winding
B= right handed winding
C= converging or diverging to the center. |
