摘要:
A method of bonding a substantially planar sheet material to a corrugated sheet material using an automated process the method characterised by the steps of a) applying adhesive in discrete amounts to the contact points of the corrugated sheet material, and b) holding the sheet materials together until a bond is formed between them.

A machine for producing corrugated paper has a machine frame, a fluted roller and a glue application roller, which can be placed against the fluted roller and between the surface of which and the fluting the paper web to be provided with a corrugation and to be partially glued can be guided through. Provided between the fluted roller and the glue application roller and to the side of the fluting is at least one spacer, which maintains a safety gap with a gap width d between the surface of the glue application roller and the fluting, the gap width d being smaller than the smallest thickness of the paper web.
摘要:
A repulpable moisture resistant poultry box having a composite structure with a fluted medium, a top backing board secured to one side of the fluted medium and a bottom backing board secured to the other side of the fluted medium. The backing boards and the fluted medium are impregnated with a hydrogenated triglyceride. The backing boards each have an outer surface coated with PET to provide moisture resistance repulpable and recyclable box.
摘要:
A method for automatically setting the rider roll/glue applicator roll gap for the single face web on a glue machine senses a forward drag that the single face web, operating at corrugator speed, exerts on the glue applicator roll, driven at an underspeed, after bringing the flute tips of the single face web into contact with the glue applicator roll by adjusting the position of the rider roll. Changes in forward drag exerted on the glue applicator roll are monitored and related directly to glue applicator roll drive current to provide a slight compression of the single face web between the rider roll and the glue applicator roll. Preferably, the glue applicator roll uses a regenerative drive and the target drive current command in a feedback control system to cause the gap to be adjusted to achieve the desired slight compression of the web flutes and to maintain the glue applicator roll under speed.
摘要:
Method for manufacturing corrugated board or the like, whereby different material strips (3-6) are fastened together by means of a bonding agent, whereby one or several material strips (3-6) are guided along at least one press-on device (15-16), where they are guided over one or several elements (10-14), in particular supporting elements, and are pressed against them by means of a series of movable press-on parts (19), wherein for pressing on these press-on parts (19), use is made of magnetic forces.
摘要:
A continuous, fully automated and highly productive system for the production of open core elements utilizes various formations of fluted input webs which are cut into strips, glued, cross-transferred, and serially upended for placement against preceding strips to build up an open core element. The open core elements are useful in the manufacture of structural members such as doors, floor panels and all panels.
摘要:
The invention relates to a machine for the manufacture of a web of corrugated board which is conveyed in a working direction and comprises at least one smooth liner and at least one corrugated medium that has corrugation tips and corrugation troughs, the corrugated medium being applied by adhesion to the at least one liner at least in the vicinity of the corrugation troughs, wherein a quality assessment device for assessment of the quality of the adhesive bond between the at least one liner and the at least one corrugated medium is provided, which comprises at least one ultrasonic transmitter that is disposed on one side of the web of corrugated board and at least one ultrasonic receiver that is disposed on the opposite side of the web of corrugated board and is allocated to the at least one ultrasonic transmitter; and a control anti evaluation unit which, in a manner for data transmission, is connected to the at least one ultrasonic receiver for evaluation of the signal of the ultrasonic receiver.
摘要:
A corrugator glue machine is provided having a web tension nulling mechanism that is effective to cancel out web tension-effect forces exerted on machine members, such as rollers, so these forces to not substantially interfere with the application of glue to the exposed flute crests of a single-faced corrugated web in the glue machine.
