FIELD: machine building. ^ SUBSTANCE: invention refers to spreading head in machines for spreading waffle sheets. A spreading roller and a counter-roller in the spreading head are set off relative to each other and can be axially shifted relative to each other. In the region of the receiving space the first side limiting wall is packed by means of radial sealing relative to circumferential surface of the spreading roller. The second side limiting wall is packed by means of radial sealing relative to circumferential surface of the counter-roller. ^ EFFECT: facilitating change of length of between-rollers gap with simple measures without replacement of rollers. ^ 4 cl, 9 dwg |
