Abstract:
A method for receiving discrete parts travelling at a first speed and applying said parts to a substrate web travelling at a second speed, said method comprising the steps of:a) providing a rotatable transferring means for receiving said discrete parts in a receiving zone and applying said parts to said substrate web in an application zone; andb) rotating said transferring means at a substantially constant first surface speed which substantially equals said first speed of said discrete parts as said discrete parts are received in said receiving zone and a substantially constant second surface speed which substantially equals said second speed of said substrate web as said discrete parts are applied to said substrate web in said application zone wherein said rotating is provided by a drive means which includes at least one rotatable noncircular drive gear and a driven means which includes at least one rotatable noncircular driven gear, said drive gear being configured to engage and rotate said driven gear which rotates said transferring means at a variable speed.
