A method for precisely aligning a product to be stapled in relation to a stapling
device in a gatherer stapler, includes the steps of determining an exact position
of the product to be stapled, comparing the determined position with an expected
position of the product, supplying a determined positional deviation to a drive
as a control variable and performing a compensatory movement by controlling at
least one of respective drives of the gathering chain and of the stapling device
so that the determined positional deviation is compensated for at the start of
the stapling operation. A device for performing the method and a gatherer stapler
are also provided.
