This invention relates to an apparatus for transferring a discrete portion of a first web traveling at a first speed onto a second web traveling a second speed. The apparatus includes a converting mechanism capable of forming at least one discrete portion out of the first web. An anvil roll is positioned in close proximity to the converting mechanism and can travel at a rotational speed equal to the first speed. The anvil roll is a vacuum roll that is capable of directing the discrete portion away from the converting mechanism. A transfer roll 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.

An apparatus and method is described herein for applying labels to containers. The apparatus includes a guidance mechanism configured to provide a path for receiving a plurality of labels having a back surface with a fluid activatable adhesive that is non-tacky until activated, an adhesive activation station aligned with at least a portion of the guidance mechanism and configured to apply to the back surface of said labels a fluid to activate said adhesive along said back surface of said labels, and a label application station configured to apply at least one of said labels with said activated adhesive onto an exterior surface of a corresponding object located on a rotatable platform. The guidance mechanism includes at least one rotatable transfer member having a plurality of pallets. Each of the pallets includes multiple openings for communication of suction to enable at least one of the pallets to receive and releasably secure a front of the labels onto at least one pallet, and one or more rollers connected to each of the pallets by one or more tunable complaint members. The label application station includes a servo motor configured to drive a linear speed and a rotational direction of the platform.

An apparatus and method is described herein for automatically labeling using labels having a fluid activatable adhesive along the back surface of such label. The apparatus has multiple pallets each being positionable with the lowermost label of a stack of one or more labels to releasably secure by suction the label against the pallet, and multiple pads each being positionable with respect to pallets to receive labels from the pallets and then releasably retain such labels until application onto containers. Fluid for activating adhesive is applied by an applicator onto labels retained upon the pad to change the fluid activatable adhesive along the label's back surface from a non-tacky state to a tacky state just prior to application of the label onto container.

This invention relates to a method of transferring a discrete portion of a first web onto a second web. The method includes advancing the first web at a first speed and advancing the second web at a second speed. The first web is directed to a converting mechanism where a discrete portion is formed. The discrete portion is then transferred onto a vacuum anvil roll that is rotating at the speed of the first web. The method further includes transferring the discrete portion from the vacuum anvil onto a transfer roll that is also traveling at the first speed. The transfer roll is a vacuum roll that is driven by a servomotor and is capable of changing speeds quickly. The speed of the transfer roll is varied to match the speed of the second web and the discrete portion is transferred onto the second web.

A glue delivery system and method for providing precise application of glue on a substrate. A bead of glue is extruded from a first glue chamber through a gun to a leading edge of the substrate. A trailing edge of the substrate is blown off and over to the nozzle to receive a smear of glue from a second glue chamber. A gear pump is controlled by a servo drive that is connected to a servomotor utilizing a gear reducer. The pump regulates the extrusion of the glue onto the substrate that is programmed with empirical data of gear reducer ratio at which the glue flows within a constant speed, torque, current, speed and position of the glue. The empirical data is provided to a programmable logic circuit to achieve a precise pressure related to volume of a glue deposition and speed of the substrate onto which the glue is applied.

A system includes an applicator including at least one aperture configured to apply fluid to a back side of a label, the back side of the label including a fluid activatable adhesive; a speed detector configured to detect a speed of the label along a label path through the system; and a control system configured to control fluid application to the label based on the speed of the label. The label may be moved by two different label drives while fluid is applied to the label by the applicator, and a speed at which the label is moved by a first drive may be used to control a speed at which the label is moved by a second drive.
