AUTHOR’S NOTE
The purpose of this manual is to provide a practical guide for glue users, to help in eliminating waste and improving the quality of product.
That there is an enormous waste due to improper preparation and use of glue is well known to all who are in touch with the subject.
Some authorities estimate that 70% of the glue used in the United States is improperly handled. The actual waste is said to be in excess of 25% of the amount of glue used; to say nothing of the loss due to imperfect condition of the completed work.
The writer knows from actual experience that many glue users are ignorant of the proper methods to be employed; and that many others are careless, or indifferent.
The handling of glue is a subject on which much new light has been shed in recent years. There is no longer any reason why the glue user should not know the correct methods to follow.
This treatise is intended as a handbook for the glue user who is interested in increasing the efficiency of his operations.
Technical expressions have been avoided, the whole matter being set forth as much as possible in the everyday terms in familiar use in the glue-room.
So far as the author can learn, from an extended investigation, no book has been published on this subject exactly answering the needs of the average glue user. Several excellent works are available which would be interesting to a man technically trained in the subject; but although they embody many helpful suggestions, they are not in such form as to be of the greatest value to the practical man. No pretense is made for the present manual of disclosing new facts; but rather of assembling in handy and easy reference form a summary of the best modern practice which the glue user of today may rely upon as a safe and convenient guide.
