Abstract:
A spreader for spreading a fluid, such as an adhesive, in a thin layer on a surface including a spreader housing and a plurality of outlet nozzles, which are arranged at regular intervals along one side of the spreader housing, and which are connected to a feeding channel system accommodated in the housing. The feeding channel system communicates with an inlet opening for the fluid. The nozzles, the feeding channel system thereof and the inlet opening are shaped in a separate lining detachably secured in the housing, the housing including cavities for receiving the lining and being able to firmly clamp around the lining in use, and whereby at least one opening is provided in the housing, where the nozzles project from the interior of the housing through the opening.
Abstract:
A suck back valve is equipped with a coupling having a fluid passage with a first port formed in one end, and a second port formed in another end thereof, a suck back mechanism for sucking a pressurized fluid inside the fluid passage under a displacement action of a second diaphragm which is displaced by a pilot pressure, and an ON/OFF valve disposed coaxially with the second diaphragm for opening and closing the fluid passage by displacement and movement thereof with the second diaphragm.
Abstract:
A meltblowing die assembly featuring a preassembled die tip assembly permitting the rapid exchange thereof. The preassembled die tip assembly includes a die tip having a triangular nosepiece, a member mounted on the die tip assembly for conforming the die tip to the die body, and a pair of air plates mounted on the die tip and in combination with the nosepiece define converging air slots.
Abstract:
A method and adhesive dispensing apparatus for applying continuous, parallel rows of adhesive onto the center portion of the backing sheet of a disposable diaper and intermittent, parallel rows of adhesive on the outer portions of the backing sheet on either side of the center portion. The apparatus includes a slot nozzle, divided into two center sections and two end sections, which is formed with flow passageways for each section having a coat hanger profile including a plurality of spaced, discharge orifices to form the parallel adhesive rows. A valving arrangement including solenoid-operated center dispensing valves for each center section of the nozzle, and solenoid-operated dispensing and recirculation valve pairs for each end section of the nozzle, controls the flow of adhesive to the nozzle. The center dispensing valves are continuously opened during an operating run to apply continuous adhesive beads on the center portion of the backing sheet, and the outer dispensing valves are opened and closed intermittently to form gaps on the end portions of the backing sheet without adhesive where the leg holes of the diaper are subsequently cut to form individual diapers.
Abstract:
A pumping device for spacer material, such as TPS (Thermoplastic Spacer) material for insulated glazing units (IGUs). The pumping device includes a pumping unit driven by a control signal, including a cylinder driven by the control signal, a rod reciprocating at regular intervals by the operation of the cylinder, a piston installed at an end of the rod and reciprocating synchronously with the rod to pump spacer material in the drum in predetermined amounts, a through-hole formed for the passage of the piston and rod, a pressure plate sealingly pressing the spacer material in the drum and surrounding the rod, and a pumping housing sealingly enclosing the rod. The pressure plate includes multiple suction holes formed for the passage of spacer material in the drum, and these suction holes communicate with the through-hole.
Abstract:
The present disclosure relates to a method and a filling machine for portioning pasty masses for the purpose of food production, wherein a pasty mass is fed by the filling machine into the filling flow divider, where it is separated into a plurality of mass flows and discharged in portions in the discharge direction. At the end of each portion the mass flow is sucked back in a direction opposite to the discharge direction.
Abstract:
A coating device for dip coating an ophthalmic lens is provided. The coating device includes a lacquer basin for receiving a lacquer mixture, which contains a lacquer and a solvent. The coating device has an overflow channel arranged at the lacquer basin for collecting the lacquer mixture overflowing from the lacquer basin, and a tubing system for providing an influx of the lacquer mixture to the lacquer basin, which is connected to the overflow channel for collecting a return flux of the lacquer mixture from the overflow channel to enable circulation of the lacquer mixture through the lacquer basin, the overflow channel, and the tubing system. The coating device includes a supply unit for dosing the lacquer and the solvent for the lacquer mixture, which is connected to the tubing system and configured to feed at least one of the lacquer and the solvent directly into the tubing system.

Abstract:
An intermittent valve device includes: an intermittent valve capable of switching between a first state in which a coating material is supplied to a die that applies the coating material onto a material to be coated and a second state in which the supply of the coating material is stopped; and a drive unit that switches the first state and the second state of the intermittent valve. The drive unit includes a cam that rotates in one direction with a circumferential surface of the cam connected to the intermittent valve. The cam includes, on the circumferential surface, a first shape part that places the intermittent valve in the first state, and a second shape part that places the intermittent valve in the second state.
Abstract:
An intermittent coating device includes a die used to apply a coating material onto a material to be coated, and a first intermittent valve and a second intermittent valve capable of switching between a first state in which the coating material is supplied to the die and a second state in which the supply of the coating material is stopped. The first intermittent valve and the second intermittent valve have different timings of switching between the first state and the second state.
