Computer controlled apparatus and method for inserting mail into envelopes
First Claim
1. A method of producing at least one control signal data look-up table for a mail insertion machine having a 360 degree cycle of operation and capable of variable operating speeds within a given cycle, said mail insertion machine further having a plurality of sub-assemblies with pre-determined electro-mechanical lag times for extending and retracting mechanical components within the mail insertion process wherein an operating speed corresponds to a control signal data look-up table, with at least one of the sub-assemblies including a component driven in reciprocating fashion, said method comprising the steps of:
- (a) creating a baseline control signal data look-up table for a first operating speed for said sub-assemblies based upon the pre-determined electromechanical lag times, said look-up table comprising a start angle and a stop angle within the 360 degree cycle of operation for said sub-assemblies;
(b) compensating the start and stop angles of said sub-assemblies for a second operating speed based upon the pre-determined electromechanical lag times for extending and retracting mechanical components and the first operating speed; and
(c) creating a second control signal data look-up table by writing said compensated start and stop angles that correspond to the second operating speed into said second control signal data look-up table.

Abstract
A method of producing at least one control signal data look-up table for a mail insertion machine having a 360 degree cycle of operation and capable of variable operating speeds within a given cycle. The mail insertion machine possesses predetermined electro-mechanical lag times for extending and retracting mechanical components. The method entails creating a baseline control signal data look-up table for a first operating speed based upon pre-determined electro-mechanical lag times. The look-up table comprises a start angle and a stop angle within the 360 degree cycle of operation. The start and stop angles are then compensated for a second operating speed based upon the pre-determined electro-mechanical lag times for extending and retracting mechanical components and the first operating speed. A second control signal data look-up table is then created by writing the compensated start and stop angles that correspond to the second operating speed into the second control signal data look-up table. Look-up table data is stored in computer memory. Additional control signal data look-up tables can be instantaneously created upon selection of a different desired operating speed.
