The disclosure relates to a spreading unit having a shaper for spreading viscous material, in particular sealing material, on a component, wherein the shaper has a first shaping contour for shaping the viscous material in the process of the spreading, wherein at least a second shaping contour of the shaper for shaping the viscous material can be brought by means of an actuator, in a direction of spreading, into superimposition with the first shaping contour, so that a shape of the shaper is adjustable during an application process.

The present invention discloses an automatic gluing apparatus for a fixed shaft-type rewinding reel, including a gluing mechanism and a glue supply mechanism, where the gluing mechanism includes a mounting plate, a side of the mounting plate is provided with a glue scraping head configured to apply a glue to the rewinding reel, a glue-scraping drive assembly that is configured to drive the glue scraping head to approach or leave the rewinding reel is disposed between the glue scraping head and the mounting plate, and the glue scraping head includes a glue scraping surface fitting with a shape of an outer surface of the rewinding reel; the glue supply mechanism disposed on a side of the mounting plate, connected to the glue scraping head. The gluing mechanism can resolve the inconvenience of the manual gluing operation, improve the efficiency of electrode plate rewinding.
