摘要:
Improved method and apparatus for forming soft, bulky absorbent webs including thermoplastic fibers. The web is bonded under conditions that heat the thermoplastic fibers to produce web bonding while avoiding direct contact with the heat source. The apparatus includes a pair of foraminous belts or wires between which the web or webs to be bonded are enclosed. The construction of the foraminous wires and belts is selected to produce the desired degree of bonding and yet maintain separation between the subsequently applied heat source and the web or webs. The combination of the web and belts or wires is then directed under tension to a heat source which may be, for example, a series of heated cans, and the opposite sides of the combination are alternately contacted by the surfaces. After heating, the web is allowed to cool and retains its bonded configuration determined by the structure of the wires or belts and the content of the web. Examples of webs which may be so bonded include pulp fluff having mixed therein thermoplastic bonding fibers such as polypropylene/polyethylene biconstituents, for example, Chisso ES. The construction of the belt or wires preferably is such that at least about 20% open area is provided upon contact with the web for sufficient strength properties to be obtained. In alternative embodiments, multiple webs of the same or different compositions may be fed between the wires or belts and laminates produced. Webs of the invention retain highly desirable absorbency properties since the open structure is maintained to a high degree by avoiding direct contact with the heat source that would otherwise produce excessive fusing and overbonding of the webs.

摘要:
A skin-friendly hook component of a hook and loop fastener that reduces or eliminates the occurrence of red-marking and/or irritation if brought into contact with a wearer's skin. In one embodiment, the hook component can have a relatively large top surface area among the hooks with respect to a surface area of the hook backing. In another embodiment, the hook backing is highly flexible, attributable to a flexible resin and/or modified topography. In yet another embodiment, a highly flexible polymer, or polymers, can be used to make individual hooks such that the hooks bend in response to a minimum amount of pressure. Various illustrated hook tapes have features along their edges to enhance skin-friendliness. A skin-friendly hook component results any combination of the disclosed embodiments. The hook component is particularly beneficial when used in absorbent articles.

A system for cutting blocks of food product into bars of substantially equal weight. The system includes a cutter conveyor configured to receive incoming blocks of food product and move the blocks along an in-line processing path in a plane for cutting; a programmable logic controller coupled to the cutter conveyor; and, multiple stations associated with the cutter conveyor. One such station is a camera vision system configured to create an image of the slab portion, and further including a camera controller coupled to the vision system and the PLC, and configured to determine an optimized cut solution of the slab portion from the image and data related to the food product, and is configured to provide the cut solution to the PLC. The PLC is configured to control the cutting of the food product, based on the optimized cut solution, into bars of substantially equal weight.

An easy-to-grip diaper fastener tab has an array of hook-shaped fastener elements arranged in parallel rows, each fastener element including a stem and a crook extending from the stem in a predetermined direction to a distal tip. The array includes a plurality of rows of fastener elements arranged such that, in each row, all of the crooks face in the same direction and parallel to the direction of the row, with the crooks of adjacent rows facing in opposite directions. The longitudinal spacing between opposing tips of adjacent hooks of adjacent rows is greater in a first portion of the array than the longitudinal spacing between opposing tips of adjacent hooks of adjacent rows in a second portion of the array, such that the crooks of the hooks of the first portion are more exposed for engaging loops than the crooks of the hooks of the second portion. Methods and molds for forming such arrays are also provided.
摘要:
A unified session detail records of a multi-hop session is provided. The multi-hop session may be established through multiple nodes in a VoIP network. Each node may generate session detail records for the legs of the multi-hop session that are connected to the node. The nodes on the path of the multi-hop call may send the record to a single node to consolidate the session detail records of the legs of the multi-hop call in the single node so that the single node can provide unified session detail records of the multi-hop session. By providing unified session detail records, the user does not need to track down the nodes that are on the path of the multi-hop call to obtain the session detail records of the multi-hop session.
