    • This invention relates to an apparatus for transferring a discrete portion (26) of a first web (14) traveling at a first speed onto a second web (48) traveling a second speed. The apparatus includes a converting mechanism (24) capable of forming at least one discrete portion out of the first web. An anvil roll (32) is positioned in close proximity to the converting mechanism and can travel at a rotational speed equal to the first speed. The anvil roll (40) is a vacuum roll that is capable of directing the discrete portion away from the converting mechanism. A transfer roll (66) is arranged in close proximity to the anvil roll and initially travels at a rotational speed equal to the first speed. The transfer roll forms a gap with the anvil roll through which the discrete portion can pass. The transfer roll is also a vacuum roll that is capable of directing the discrete portion away from the anvil roll. The transfer roll is capable of changing rotational speed to match the second speed during a single revolution. A backing roll is arranged in close proximity to the transfer roll and travels at a rotational speed equal to the second speed. The backing roll cooperates with the transfer roll to combine the discrete portion with the second web.
    • 本发明涉及一种用于将以第一速度行进的第一腹板(14)的离散部分(26)传送到第二速度行进的第二腹板(48)上的装置。 该装置包括能够形成离开第一网的至少一个离散部分的转换机构(24)。 砧辊(32)定位成靠近转换机构,并且可以以等于第一速度的转速行进。 砧辊(40)是能够将离散部分远离转换机构的真空辊。 传送辊(66)被布置成靠近砧辊,并且以等于第一速度的转速开始行进。 转印辊与砧辊形成间隔,离散部分可以通过该间隙通过。 转印辊也是能够将离散部分远离砧辊的真空辊。 传送辊能够在单次旋转期间改变旋转速度以匹配第二速度。 背衬辊布置成靠近传送辊并以等于第二速度的转速行进。 背衬辊与转印辊配合,以将离散部分与第二幅材组合。
