摘要：
The invention relates to a sizer (10), which comprises at least one hard-surfaced sizing roll (11; 12), application means (22) configured to apply a sizing agent layer (A) onto the surface of the hard-surfaced sizing roll (11), an application element (20) configured to smoothen the sizing agent layer (A) to a smooth sizing agent layer (AS). The application element (20) is a soft-surfaced application element (20) and hardness of the soft-surfaced application element (20) is substantially lower than hardness of the hard-surfaced sizing roll (11).
