Clampless bar mechanism for a paper bag bottoming mechanism
View Patent ↗A paper bag bottoming mechanism having a bottoming drum having a first end, a second end, and a sidewall disposed therebetween, a bar affixed to the bottoming drum, the bar having a first end and a second end, a first guide block attached to the first end of the bar and a second guide block attached to the second end of the bar, a first slideable finger attached to the first guide block and a second slideable finger attached to the second guide block, and a first actuating mechanism communicating with the first slideable finger for actuating the first slideable finger and a second actuating mechanism communicating with the second slideable finger for actuating the second slideable finger. Also disclosed is a method for making a using a clampless bar mechanism.
1. A paper bag bottoming mechanism comprising:
a bottoming drum having a first end, a second end, and a sidewall disposed therebetween,
a bar affixed to the bottoming drum, the bar having a first end and a second end,
a first guide block attached to the first end of the bar and a second guide block attached to the second end of the bar,
a first slideable finger attached to the first guide block for translational movement with respect thereto and a second slideable finger attached to the second guide block for translational movement with respect thereto, and
a first actuating mechanism communicating with the first slideable finger for actuating the first slideable finger, and a second actuating mechanism communicating with the second slideable finger for actuating the second slideable finger.
2. The paper bag bottoming mechanism according to claim 1 wherein the first and second actuating mechanisms are pneumatic cylinders.
3. The paper bag bottoming mechanism according to claim 1 wherein the first and second actuating mechanisms are electrical actuators.
4. The paper bag bottoming mechanism according to claim 1 further comprising a synchronizing device communicating with the first and second actuating mechanisms for controlling actuator timing.
5. The paper bag bottoming mechanism according to claim 1 further comprising a pressurized air device having an air inlet and an air outlet, the pressurized air device located adjacent the bottoming drum.
6. The paper bag bottoming mechanism according to claim 5 , wherein the outlet of the pressurized air device is orientated to blow air at the bottoming drum sidewall.
7. The paper bag bottoming mechanism according to claim 5 , wherein the outlet of the pressurized air device is orientated to blow air along tangentially to the bottoming drum sidewall.
