GLUED LAP ADHESIVES
Astro Packaging has high-performance adhesives systems for the entire spectrum of corrugating machines and applicators, and for the materials to be bonded. Our constant contact with machine and applicator manufacturers has resulted in adhesives that work in any machine type. Read more in this PDF...
Testing adhesives used in glued lap joints of corrugated fiberboard containers
This method describes a procedure for evaluating the adhesive used in glued lap joints of corrugated containers. This method describes a laboratory procedure for evaluating glued lap adhesive applied to laboratory-prepared specimens made from the linerboard to be used in the manufacture of corrugated containers. A separate testing procedure for the finished containers is TAPPI T 813 “Tensile Test for the Manufacturer’s Joint of Fiberboard Shipping Containers.”
This procedure measures heat resistance, water resistance, and cold resistance of the adhesive used in glued lap joints.
Typically used for corrugators and folding cartons!Also used for boat assembly: Glued lapstrake is a contemporary method of building traditional lapstrake boats. Epoxy replaces cinch nails or rivets used to edge join the planks lengthwise. Like strip built boats, glued lap construction relies on forms when hanging planks and stems to attach them to at the ends. In addition, some kind of hog keel or keelson to land the garboard planks helps significantly in aligning these bottom planks. The end result is a beautifully styled traditional looking boat with no evidence of nails or rivets and doesn't require ribs for strength like traditionally constructed models.
Plywood is often used instead of traditional planking in some lapstrake designs. Glued plywood lapstrake is a fairly simple technique, combining time-proven designs producing a strong, durable boat, and quite light for its size. These are quite do-able by the amateur, though not instant boats by any means. There is a lot of work getting the planks shaped properly and there is plenty of glue that needs cleanup between the laps. This produces a boat of traditional form with advantages for modern boating over traditional lapstrake.
In the thinner dimensions, high quality marine plywood is stronger than conventional planking of equal thickness. This can be attributed to the cross wise lamination of veneers. Thickness as result can be proportionally reduced when interpreting traditional plans. Plywood thickness has its limitations with respect to the minimum bending radius. It is feasible to cut the individual planks of a lapstrake hull out of plywood sheets.
