Continuous motion package forming machine

A continuous motion processing machine comprising:

• a framework;
• conveyor means supported on said framework adapted to travel through a processing zone at a constant rate;
• first web supply means on said framework adapted to deliver a first web to said conveyor means to carry said web through said processing zone at a constant rate of advancement said first web supply means including a first motor having a rotatable output shaft positionable in a plurality of positions during a predetermined distance of web advancement;
• means to condition said first web to receive product to be packaged;
• second web supply means to supply a second web in overlying relation to said first web;
• means to connect said webs together for further movement through said zone at said constant rate;
• at least one tooling carriage;
• drive linkage including a rotatable power input shaft, said linkage being connected to said carriage to move said carriage in a repetitive cyclic path;
• processing tooling carried by said carriage adapted to perform processing steps on said webs in said processing zone during an increment of said cycle of carriage movement;
• control means connected to said power input shaft to move said carriage through said repetitive cyclic path in a predetermined period of time;
• said control means further including means to sense specific positions of said shaft of said first motor and to vary the speed of rotation of said power input shaft during said predetermined time period in relation to the position of said shaft of said first motor during said predetermined distance of web advancement.
