Abstract
Abstract A method for manufacturing corrugated angle members. These members are made of heavy paper, for example, and serve as protective reinforcements in relatively large packages containing appliances and the like, so that the corrugated angle members by engaging the appliances within the container of the package will protect the appliances against damage. A plurality of corrugated plies are glued to each other while being longitudinally angled to a gradually increasing extent by a forming means which provides the glued-together corrugated plies with a preselected angular cross section. Then the angled corrugated structure is dried while conveyed by a conveyer means through a heat tunnel. Thereafter, the corrugated structure is cut by a cutting means to preselected lengths.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
141 words
In a method for manufacturing a corrugated angle member, the steps of gluing together a plurality of corrugated plies which are initially flat and unscored, in their glued-together condition, to provide the member with a preselected thickness, then, before the glue has dried and set and while the plies remain unscored, longitudinally angling the glued-together plies to a gradually increasing extent until the plies have a preselected angular cross section, then drying the glue to set the latter with the plies remaining in their angled condition, and finally cutting the joined, angled plies, after the glue has dried and set, to preselected lengths, said steps being carried out one after the other without interruption in a fully continuous manner, so that the plies are in continuous movement from the time that they are glued together until the predetermined lengths are cut.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
32 words
In a method as recited in claim 1 and wherein the cutting of the angled plies is carried out without relative movement between the angled plies and the structure which cuts therethrough.
Claim 4
Dependent Claim
44 words
In a method as recited in claim 1 and wherein the angled plies have a pair of webs which are situated at a predetermined angle with respect to each other, and including the step of forming a miter notch in one of said webs.
Claim 5
Dependent Claim
19 words
In a method as recited in claim 3 and wherein the miter notch is punched through said one web.
