THE PACKING OF WINDOW CHANNELLING.
A New Method of Manufacture Which Enables Velvet-lined Rubber Channelling to be Easily Handled.
AA-UCH difficulty has been :experi_LVI.enced in the past by many bodybuilders in connection with the storage of velvet-lined channelling for window rune." This has been mainly owing to the fact that the article in question has had to be manufactured by a method of extrusion and the rubber to undergo this process, naturally, had to contain an unusual percentage of chalk in order
that it should not be too springy.' Hence, if the channelling were folded, in many cases it rapidly lost its correct shape and became twisted and wavy, and even when placing it in position in the body pillar it did not always assume the correct shape. Moreover, owing to these difficulties and to post office regulations governing the size of parcels, the channelling had to be packed in lengths of 3 ft. or under when being delivered from the manufacturer.
It will thus be seen that the space taken up by any length of this material adequate for the coachbuilder's purpose must be considerable, especially owing to the necessity for keeping stocks of channelling to suit 1-in., ?-6-in. and i-in. glass.
The Rawlings Manufacturing Co., Ltd., 1-11, Larch Road, Palham, Lon
don, S.W.12, has been fully alive to these difficulties, both from its own and from the bodybuilder's points of view, and Mr. A. E. Outfield, the commercial manager of this concern, has patents pending for a channelling which is made by an entirely new process. With this invention the rubber is taken in flat strips and run through a machine which makes two parallel scores in it. The rubber, which is of a more springy quality than that formerly used, is then tined with velvet and, when ready for packing, can be rolled and secured. It is stated that in this form 14,000 ft. can be stored in a box having a capacity of 1 cubic yard.
When the bodybuilder wishes to use the channelling, he has only to press it into a window run of any standard size and it assumes the correct shape for use, making a perfect and silent run.
Another advantage, apart from the lower price, which, we learn, will result from simplifying the method of manufacture, is that this type of channelling can be used for fencing the windows or as a cant rail rubber.
