For example, in the various aspects of the invention, the profile of the noncircular gears 54 and 62 is analytically designed such that the rotatable transfer assembly 40 receives discrete the parts 32 in the taking zone 42 while maintaining a constant surface speed substantially equal to the incoming speed of the parts 32. Moreover, the profile of the noncircular gears 54 and 62 is designed such that the surface speed of the rotatable transfer assembly 40 changes to a second constant surface speed as the rotatable transfer assembly 40 moves from the taking zone 42 to the transfer zone 44. The term “surface speed,” as used herein, refers to the speed of the circumferential, outer peripheral surface of the transfer assembly 40 as defined by arcuate outer surfaces 74 of the respective transport heads 46. The profile of the noncircular gears can be designed such that the speed of the discrete parts 32 being transferred is substantially equal to the speed of the substrate web 34 as the discrete parts are applied to the substrate web in the transfer zone 44. The surface speed of the transfer assembly 40 is maintained substantially constant in the taking zone 42 and the transfer zone 44 for from at least about 0 to about 300 degrees of rotation, desirably from about 10 to about 300 degrees of rotation, and more desirably from about 120 to about 240 degrees of rotation of the transfer assembly 40. In addition, the surface speed increase or decrease of the transfer assembly 40 as it moves from the taking zone 42 to the transfer zone 44 defines a speed ratio of from at least about 0.9:1 to about 20:1, desirably from about 0.9:1 to about 10:1, and more desirably from about 0.9:1 to about 4:1. The term “speed ratio”, as used herein, defines the ratio of the surface speed of the transfer assembly 40 as the parts 32 are applied to the substrate web 34 to the surface speed of the transfer assembly 40 as the parts 32 are taken.
As seen in FIG. 16 the arcuate outer surface 174 of the transport head is oriented transverse to the direction of travel of the incoming webs 136 at the respective transport head. Suction is activated on the taking sections of the transport head 146C as transport head 146C rotates into position to take the incoming webs onto its taking sections. As the transfer assembly continues to rotate about its horizontal axis 178, the taking sections of the transport head 146C take and hold corresponding portions of the webs 136, thus continuing the drawing of the webs 136 into the transfer assembly. Accordingly, the leading edge of each part 132 is oriented at an angle “A” transverse to the direction in which the part is travelling when the part is taken onto the transport head in taking zone 142.
