Fold strong papers correctly
This tip I wrote for card makers, paper lovers and those who always wanted to know!
Especially at Christmas time so many cards lovingly created by hand or designed a blank model itself. When kinking such a card it can then come to nasty surprises: The card is unruly and is difficult to fold and / or it breaks along the fold line on one of the surfaces (top or bottom), so that it is almost unusable. This is super easy to avoid if you know the following things and heeded in use.
Things to consider:
(Also) paper has - like fabric z. B. - a kind of threadline? - but in paper you call him?direction?. Although there are no interwoven or entangled textile threads, but in papermaking, the wood fibers used are also brought in a particular direction that the bookbinder must observe when he z. B. Papers used, d. H. describe or print them and then put them together to a book. The paper fibers should necessarily be aligned parallel to the later spine and then always run vertically - from top to bottom (in reading direction) - just as with fabrics ... We know this from the bookstore when leafing through books or even small calendars - some nestle to the personal hand shape and use, can be turned around great and the book can close especially well and permanently. Other - especially cheap - books, on the other hand, lock themselves when they are taken in and the pages tend to pop up again when the book is closed. The leaves are downright stubborn here, because the fibers do not run parallel to the book spine when merging into a whole, but across it. :-(
Recognize direction of paper:
1. One way, the direction recognizing paper is the following: Take a piece of cardboard, paper ... in both hands and bend it (test 1) carefully from left to right and feel how light or heavy it is. Then turn the paper 90 degrees and do the bending test (2) again. There is a big difference to be felt: In one of the two directions (Test 1 or Test 2) the paper is supple: only now the fibers pass between our hands from top to bottom so that we can gently press the edges of the paper against each other, because we do not push against the fibers, but they can adapt to our pressure. In case 2, the fibers of the paper run from right to left so that we feel a slight resistance when pressed.
By the way, handmade paper is not subject to any direction of movement due to its hand-creation. Here, the fibers are deliberately criss-crossed in paper making? which gives the paper its unerring charm! Also Nepal papers, Chinese flower paper or Japanese origami papers also have no direction.
2. At this point the so-called. Fingernail test to mention I still quite nice: If you touch the paper carefully between two nails on two adjacent edges (not destroyed), arise at one of the edge waves: Only here the fibers run in the direction of the waves - the direction is therefore parallel to the waves!
3. Another way to find out the direction? Tearing the paper on two vertical edges: Contrary to the direction of rotation, no straight tearing is possible - in parallel yes!
But now for kinking or folding or even creasing a box / a card:
If one does not do this activity with respect to the fibers and their reaction to pressure, the card may at the suction. Break fold, If you have designed them before, the whole work is free and it flows especially in children tears ...
If one kinks cardboard / paper, the material is stretched on the outer surface and simultaneously compressed on the other surface (inside) = compressed. The upsetting of the material would result in an ugly edge in the fold. This compression can be avoided by one in front the later folding / bending here creates a so-called RILLE, the fibers of the paper so deliberately already gently apart before kinking? This can be done with a shinbone or even with an empty ballpoint pen refill (the tool should not be sharp because the paper would be cut or torn open). This creates a groove, which the expert calls "valley fold": a deepening in the material that we know from a deep valley in nature!
Now it is clear in which direction we have to bend an already grooved map: the side that is later outside is torn lightly? - So we have to consider the already intentionally grooved side = with the valley fold outwards as an outer surface: The valley fold must therefore point outwards = we bend exactly away from her.
I love to use the alphabet as a reminder - so here too: If after wrinkling the valley fold is outside, we buck right! The word valley fold contains a? A ?, the word? Outside? also: A to a!
Likewise, after grooving on the opposite face of the carton / paper, thickening / densification of the material is seen because the fibers have been pushed in that direction. So you automatically form a small mountain here? this page is the so-called? mountain? fold. The mountain fold is always inside with a correctly folded cardboard / a piece of paper.
If you still like it now, you can even take a file folder from the bookshelf: Even on the outside you can see at the connection between the back and both cardboard boxes a big depression = the valley fold! If you then unfold the folder, inside the beautiful mountain fold is beautiful. This is exactly the case with our thin cards / papers, but only much more delicate!
Summary:
It does not matter if a card has already been bought ready-grooved or you are rilling your bow ... yourself:
It kinks so that the valley fold is out (A-a).
