FAQ

The HD150D Bottom Pasting Machine is designed for paper sack production, combining valve patching, bottom reinforcement and gluing in one production line. It has a maximum output of 150 bags per minute and handles tube widths from 340 to 550 mm. The machine supports reinforced valves, external sleeve valves and internal sleeve valves, as well as reinforcement patches on both ends of the sack bottom.

Key Features

Valve Patching for Different Sack Designs

The valve patching station supports reinforced, external sleeve and internal sleeve valve designs. It accepts valve patches 130–280 mm wide and 150–250 mm long, with paper weights of 75–100 g/m².

Inner and Outer Bottom Reinforcement

The machine automatically applies inner reinforcement patches to both ends of the sack bottom. It also applies outer reinforcement patches and is equipped with a two-colour printing machine on each side of the outer reinforcement paper tray. This configuration brings patching and printing into the bottom finishing process.

Adjustment During Operation

Differential adjustment devices are fitted to the valve patching, inner reinforcement, outer reinforcement and gluing units. Operators can adjust the position of paper and glue during operation without stopping the machine.
