  Types and Differences of Brushes Used in Case Sealers

  A case sealer is an automated machine used for carton packaging. Typically, there are two types of brushes: short brushes (also known as tape head brushes) and long brushes (used on corner-edge sealers).

  The main difference lies in their application and design: - The short brush is mounted at the rear of the sealing head (tape head) and is primarily used on straight-line (“I-seal”) case sealers. - The long brush is specifically designed for corner-edge sealers.

  In addition to their different applications, the two brushes also vary in length—the long brush is significantly longer than the short one. Due to these functional and dimensional differences, the two brush types are not interchangeable.

  

  Primary Functions of Case Sealer Brushes

  Short Brush (Tape Head Brush): Works in conjunction with the pressure roller to smooth and firmly adhere the tape onto the carton flap, ensuring a flat, wrinkle-free seal.

  

  Long Brush (Corner-Edge Sealer Brush): In addition to smoothing the tape along the side edges of the carton, it also folds over the tape tail neatly to prevent lifting or snagging.
