Abstract: An apparatus and method for rotating and transferring a discrete article. The rotation apparatus may include a rib portion defining a longitudinal rib axis. A head assembly may be positioned adjacent to the rib portion. The head assembly may include a transfer member. The transfer member may define a longitudinal transfer axis. A support member extending from the transfer member toward the rib portion may rotate about the longitudinal transfer axis. A first follower and a second follower may be operatively engaged with the support member. The first follower may include a first follower outer surface defining a first longitudinal follower axis and the second follower may include a second follower outer surface defining a second longitudinal follower axis. The first follower and the second follower may be positioned such that the first longitudinal follower axis and the second longitudinal follower axis intersect the longitudinal rib axis.

Abstract: An apparatus for applying discrete components of a first substrate to a second substrate includes a programmable servo motor having a shaft. The servo motor is programmed to rotate the shaft in a first phase and a second phase at a variable angular velocity in a single direction. The apparatus also includes a crank member connected with the shaft, a connector link connected with the crank member, and a tamper member connected with the connector link. When the shaft rotates in the first phase, the tamper member travels from a first position to a second position to displace a selected portion of the second substrate into contact with the discrete component.

Abstract: A method includes rotating a drum about an axis and rotating an anvil roll about an axis adjacent to the drum so as to form a nip there between. The drum includes a fluid nozzle and a press member, the press member having an outer surface. The anvil roll includes a compliant outer circumferential surface. First and second substrates are advanced in a machine direction onto the drum. The fluid nozzle moves radially outward and a jet of heated fluid is directed onto the substrates. The fluid nozzle retracts radially inward and the press member is shifted radially outward. The substrates are advanced through the nip and compressed between the press member and the anvil roll such that the press member deforms the compliant outer circumferential surface of the anvil roll.

Abstract: A first substrate advances in the first direction and a second substrate advances in the second direction. The first substrate advances onto an outer circumferential surface of a drum in a stretched state. The first substrate may be cut into discrete lengths of elastic substrate. The drum may be configured with vacuum to hold the discrete length of elastic substrate in a stretched state. The second substrate may advance in the second direction by a conveyor. The conveyor includes a roller having a curved outer surface that deforms the second substrate so as to define a curve in the first direction. A tamper apparatus intermittently displaces a deformed portion of the second substrate into contact with a discrete length of elastic substrate on the outer circumferential surface of the drum. The discrete length of elastic substrate bonds with the second substrate and is removed from the drum.

Abstract: An apparatus for joining substrates including a rotating drum. The drum may include an outer circumferential surface and a drum aperture in the drum outer circumferential surface. The drum may be configured to continuously advance substrates. A fluid nozzle may be moveably connected to the drum and located radially inward from the drum aperture. The fluid nozzle may be adapted to direct a fluid radially outward through the drum aperture toward the substrates. The fluid may have a temperature sufficient to at least partially melt the substrates. An anvil roll may be located adjacent the drum. The anvil roll may be adapted to rotate about an axis of rotation. A press member may be moveably connected to the drum and located radially inward from the drum aperture. The press member adapted to extend through the drum aperture to compress the substrates between the anvil roll to form a bond.

Abstract: A method of joining web portions includes advancing web portions onto a rotating drum such that the web portions overlap at an overlap area as the web portions wrap around the drum. The web portions each have a melting temperature. A fluid is heated to a temperature sufficient to at least partially melt the web portions. A fluid nozzle retracts from an aperture in the drum and a jet of the heated fluid is directed from a fluid nozzle onto the web portions at the overlap area. The heated fluid penetrates and at least partially melts the web portions. The web portions are at least partially melted using the heated fluid. A press member shifts through the aperture in the drum to compress the web portions between the pressure member and an anvil roll to join the web portions together at the overlap area.

Abstract: The apparatuses and methods herein may be configured to transport articles in the form of continuous lengths of substrates having thicknesses that varies along a machine direction and/or cross direction. The conveyance apparatuses may be configured to include a first carrier and second carrier, wherein each carrier includes an endless belt positioned adjacent to the other so as to define a nip region between the endless belts, the nip region extending in a machine direction and a cross direction. The carriers may also include compliant rollers in rolling contact with the endless belts. Each compliant roller may be elastomeric and adapted to provide a reaction force normal to the endless belt along the machine and/or cross direction of the nip region. As such, the compliant rollers help maintain and hold the endless belts in contact with both relatively thin and thick areas of the substrate advancing through the nip region.

Abstract: A rotary drum apparatus comprises a drum that is rotatable about an axis of rotation. The apparatus comprises a first set of first shell segments having a first number of first shell segments. Each first shell segment is releasably connectable with the drum and has an outer surface. The outer surfaces of the first shell segments combine to form a continuous first outer circumferential surface defining a maximum radial distance from the axis of rotation. The apparatus comprises a second set of second shell segments having a second number of second shell segments. Each second shell segment is releasably connectable with the drum and has an outer surface. The outer surfaces of the second shell segments combine to form a continuous second outer circumferential surface located within 10% of the maximum radial distance. The first number of first shell segments is greater than the second number of second shell segments.

Abstract: The present disclosure relates to methods and apparatuses for rejecting defective absorbent articles from a converting line. At a downstream portion of a converting process, a continuous length of absorbent articles may be subjected to a final knife and cut to create discrete absorbent articles advancing on a first carrier. From the first carrier, the discrete absorbent articles may be transferred to a transfer apparatus, which in turn, transfers the discrete absorbent articles to a second carrier. The transfer apparatus may include carrier members that orbit around an axis of rotation and may be adapted to receive the absorbent articles from the first carrier and transfer the absorbent articles to the second carrier. Defective absorbent articles may be detected by an inspection system, which may be operably connected with the transfer apparatus and/or the first carrier to remove the defective absorbent articles from the converting process.
