Turn bar apparatus and method for web fed envelope machine

Method for continuously introducing a web into cutting means of an envelope-making machine, said machine having a center line, a movable swivel plate and a pivot point about which said plate is adjustable, comprising:

• a. advancing a web along a first path to first horizontal directing means;
• b. directing the web to first turnover means for turning the web to edgewise orientation;
• c. turning the web to an edgewise orientation;
• d. advancing the web on its edge to vertical directing means;
• said vertical directing means being positioned on the swivel plate of the envelope-making machine;
• e. directing the web to second turnover means for turning the web to flat orientation, said second turnover means being positioned on the swivel plate of the envelope-making machine;
• f. advancing the web to second horizontal directing means said horizontal means being positioned on the swivel plate of the envelope-making machine;
• g. directing the web into cutting means of the envelope-making machine along a second path, said second path being at an angle to said first path and said second path being at a desired angle in relationship to the center line of the envelope-making machine, said second path established by adjusting the swivel plate to a desired position by pivoting said plate about a pivot point said pivot point lying on the center line of the machine.
