METHOD FOR THE PRODUCTION OF AN ELASTIC LAMINATE AND LAMINATED ELASTIC PRODUCT

A method for the production of an elastic laminate, with the following steps in a production line: coextrudeing a first web of elastic film with at least three layers, with at least two different polymer materials, to feed contemporaneously said coextruded first elastic film web and two second nonwoven webs to a thermal, binding calender, wherein the first elastic film web is arranged between said two second nonwoven webs when entering the calender; wherein said first elastic film web, during the movement from the coextrusion step to the thermal binding step, passes from a melted state, to a solidified and cold state when entering the calender, to join, through spot welding in said calender, said second nonwoven webs with respective opposite outer layers of said first elastic film web, thus producing an intermediate web, to stretch mechanically said intermediate web according to a direction transverse to the same web.

ASSEMBLY OF PREFABRICATED WALL MODULAR DECORATION AND ITS PRODUCTION AND INSTALLATION METHOD
20230088514 · 2023-03-23 ·

The present invention discloses an assembly of prefabricated wall modular decoration, comprising a conventional decorative material, a plate, a movable laminating layer and a protective layer. The conventional decorative material being mounted on the surface of the plate, a number of movable laminating layers being evenly spaced between the plate and the protective layer making a sound-insulated air gap between them, and the protective layer being mounted on the surface of the wall. The present invention also discloses an installation method for the assembly above. Due to the traditional decorative material, the plate, the active lamination layer, and the protective layer of the present invention are set to be installed on the wall in turn, together with the sound-insulated air gap within the structure, which is not only simple to manufacture and easy to install, but also has better sound absorption performance which could reduce the noise nuisance.

FRICTION TRANSMISSION BELT

A friction transmission belt includes a belt body which transmits power to a pulley. In a relationship between a friction coefficient and a slipping speed which is a difference between a speed of the belt body and a speed of the pulley, when a slipping speed at which a maximum friction coefficient is indicated is defined as a first slipping speed, a friction coefficient when the slipping speed is increased from the first slipping speed to a second slipping speed is defined as a reference friction coefficient, and a difference between the second slipping speed and the first slipping speed is 500 mm/s, a decrease rate Dm of the friction coefficient indicated by the following equation (1) with the maximum friction coefficient being denoted by μx and the reference friction coefficient being denoted by μr is not greater than 20%.


Dm=(μx−μr)/μx×100  (1)
