摘要:
A liquid dispenser. The dispenser includes reversible modular components to define selective removability and rearrangement between them and a base structure such that one or more sheets of a passing liquid-receiving substrate may receive such liquid through interchangeable liquid-dispensing orientations. The removability features include tool-free operation to facilitate quick insertion and removal of the modular components that include at least a liquid-dispensing valve assembly and a seal that is selectively engageable with the valve assembly to protect liquid-dispensing nozzles of the valve assembly from becoming clogged with residual dried liquid during periods of inactivity of the liquid dispenser. Selective movable cooperation or attachment between the modules—as well as between the modules and the base structure—facilitates flexible configurations of the dispenser, including top-down and bottom-up liquid-dispensing orientations.

The invention relates to a method of producing a product comprising a support having a long-acting adhesive and a protective tape disposed thereon, so that said adhesive can be used at a later time. The inventive method is characterised in that it consists in: determining a reference plane (P) which is close to the location of the adhesive deposit and which is either below the plane containing the lower face of the support or above the plane containing the upper face of said support; establishing the distance (D) separating the reference plane (P) and the level (N) at which the adhesive (2) is delivered, which is close to the plane containing the application face of the support; delivering the long-acting adhesive (2); delivering a protective tape (20) which is disposed on top of the adhesive (2) either simultaneously using a prefabricated transfer tape or separately; moving the support in relation to the deposit station; exerting a transverse force on the support such that one of the faces thereof is applied continuously against the reference plane (P); and exerting a pressure, counter to the transverse force, on the protective tape (20) and the adhesive (2).

The present invention relates to a system and method for transferring tissue reels. The system preferably incorporates nozzles that spray an adhesive directly onto moving tissue paper substrate, as opposed to applying adhesive directly to the reel, independent of machine speeds and basis weights of the substrate. Alternatively, the system of the present invention may also apply adhesive directly to the new reel as opposed to the tissue paper substrate. In the preferred embodiment, the new core or reel is brought up to substantially equivalent speed as the moving tissue paper substrate and placed into contact with the moving web of tissue. When the new reel is in place, the valves are activated thereby spraying adhesive across the width of moving tissue. The newly coated substrate sticks substantially immediately to the new core and cleanly tears away from the completed roll.

The present invention generally relates to a hot molten adhesive application machine. More specifically the present invention discloses a unique hot melt adhesive application machine having a novel construction whereby the reservoir of molten adhesive material is heated from within the molten adhesive. The adhesive pump, discharge hoses, and discharge applicators are heated by electrical resistance heating elements that may operate on 120 or 240 volt current. Further, a novel axial pump piston is disclosed whereby the pump cylinder bore may be machined to a lessor tolerance standard than previous pumps of this type.

A collapsible tube dispenser is disclosed for use with collapsible tubes that contain highly viscous materials, such as silicone gasket RTV. The dispenser provides two engaging plates for squeezing the sides of a collapsible tube, which causes the contents of the tube to be expressed from its open end. The dispenser also includes two handles which can be gripped by a single hand of a human user. When the handles are kept apart from one another, a collapsible tube can be inserted into the slot formed between the engaging plates of the dispenser. When the handles are squeezed together, the engaging plates apply force to the sides of the tube, thus squeezing out a very controlled amount of highly viscous material. The dispenser is very easy to use, in that it can produce a bead of highly viscous material upon a target having a very narrow line width, and having great positional accuracy.
