Abstract: Various methods and devices maintain a registration nip and a transfer nip at the same sheet feeding speed when the leading edge of a sheet is between them. These methods and devices create a buckle in the sheet by increasing the sheet feeding speed of the registration nip while maintaining the transfer nip at the original sheet feeding speed during a first portion of when the sheet is simultaneously within the registration nip and the transfer nip. Such methods and devices then decrease the sheet feeding speed of the registration nip after creating the amount of buckle in the sheet and maintain the registration nip and the transfer nip at the same sheet feeding speed to maintain that specific amount of buckle in the sheet during the remaining portion of when the sheet is simultaneously within the registration nip and the transfer nip.

Abstract translation: 当片材的前缘在它们之间时，各种方法和装置以相同的片材进给速度保持对准辊隙和转印辊隙。 这些方法和装置在片材同时位于配准辊隙和转印辊隙内的第一部分期间，通过增加对准辊隙的片材进给速度，同时保持转印辊隙处于原始片材进给速度，从而在片材中产生带扣。 这样的方法和装置然后在片材中产生带扣量之后降低对位辊隙的片材进给速度，并以相同的片材进给速度保持对准辊隙和转印辊隙，以在片材期间保持特定量的带扣 当片材同时位于配准辊隙和转印辊隙内时的剩余部分。
