An equipment system for bond-packaging an LED using a thermoplastic resin photoconverter by rolling includes: a cooperative roll-shaping and roll-cutting apparatus used for performing roll-shaping and roll-cutting on a photoconversion sheet, to form a photoconversion sheet array; and a roll-bonding apparatus used for performing roll-bonding on the photoconversion sheet array and a flip chip LED array. The cooperative roll-shaping and roll-cutting apparatus and the roll-bonding apparatus are arranged sequentially to form cooperatively linked process equipment, where the cooperative roll-shaping and roll-cutting apparatus includes a first rolling device with a protrusion array and a second rolling device with a recess array that are disposed face-to-face and aligned with each other, and the roll-bonding apparatus includes a fourth rolling device with a recess array and a third rolling device with a smooth rolling surface that are disposed face-to-face and aligned with each other.

A calender for the treatment of web-like materials, including a fixed structure adapted to support two heated rollers shaped to be connected to the fixed structure, to a drive unit and to a heating system. The calender includes automatic elements for engaging and respectively for disengaging the rollers to and from the fixed structure, the drive unit and the heating system; the automatic elements are controlled by a programmable control unit and each of the rollers has an engaging surface shaped to be engaged by mechanical elements for moving the rollers which move the rollers between the calender and one or more waiting or parking stations while the rollers are at a temperature between 50? C. and 200? C.

Methods and apparatuses for deforming a web are disclosed. In one embodiment, the method involves feeding a web into a nip that is formed between at least two intermeshing rolls. The rolls are configured for deforming a web with at least two sets of deformations that are oriented in different directions relative to the surfaces of the web.

A three-dimensional netted structure having an upper surface, a lower surface, two side surfaces a left end surface, and a right end surface, including at least a plurality of filaments helically and randomly entangled and thermally bonded together, wherein the filaments are formed out of a thermoplastic resin by extrusion molding followed by cooling with a liquid; and the netted structure is four-surface molded, the upper surface, the lower surface and the two side surfaces being molded. An apparatus and a method for manufacturing the three-dimensional netted structure.

A method for making apertures in a precursor web using a forming apparatus is described herein. The precursor web comprises a film layer and a nonwoven layer having molecular orientation and the forming apparatus comprises an arrangement of teeth. The forming apparatus heats and stretches the precursor web forming apertures therein.

The invention describes a method for manufacturing a plastic drain sheet, and a plastic drain sheet. For the purpose of manufacture, a sheet-like main body having a first surface and a second surface, spaced apart therefrom by a base sheet thickness, is provided. Grooves are introduced into the first surface and mating grooves are introduced into the second surface. The mating grooves and the grooves cross one another at crossing points. Through-openings between the grooves and the mating grooves are formed at the crossing points.
