Round Bottom Punches

These devices facilitate round-bottomed side-sealed bag production, for uses such as chicken bags. 

Examples of such devices include:

HRB Series Round Bottom Punch

This device facilitates small radii round bottomed side sealed bag production.

Salient features include:

  • Short stroke pneumatic actuation of sealing jaw
  • Secondary pneumatic jaw retraction when stopped
  • Patent pending ejection process
  • Very high performance
  • Typical radius 74mm
  • HRB-S Series Servo Round Bottom Punch.
    Additional to the features of the HRB series device, the HRB-S series round bottom punches utilize AC servo actuation of the sealing jaw for even high production speed.

HRB-BLT-Servo Series Round-Bottom Punch

Utilizing AC servo technology, the ORION HRB-BLT-Servo Series Round Bottom Punch facilitates the high speed production of round-bottomed bags at the intermittent web zone of a suitable parent side-seal plastic bag-making machine. This device seals and cuts away curved sections of film, thereby ultimately resulting in round-bottomed side-sealed bags.

Salient features include:

  • AC servo actuated sealing jaw.
  • AC servo actuated scrap removal system.
  • Very high performance.
  • Very smooth & quiet operation.
  • Pneumatically controlled seal pressure, incorporating secondary seal jaw retraction.
  • Large sealing radii possible (standard is 155mm).
  • Dual channel digital temperature control of sealing jaw.
  • Suitable for a broad range of plastic materials, including PE and PP.
  • Full safety guarding.
