The present invention is concerned with a method of fitting a belt to a filter assembly of the endless belt type having belt-tensioning means in which a belt blank, the end portions of which are at least only partially vulcanized and which have disposed therein recesses arranged to receive in friction locking manner connecting members having an end portion whose configuration corresponds to the configuration of its receiving recess, is placed in position in the assembly around said belt-tensioning means such that the ends of said belt lie adjacent each other, whereafter the connecting members are inserted in respective recesses to form an endless belt having a friction-locked joint, the ends of said belt are fully vulcanized, and the belt is tensioned. The invention also encompasses a belt blank adapted to be used in the method as given above.
A belt blank having two end portions in which are disposed recesses arranged to receive in a friction-locking manner connecting members having at least one end of similar configuration to the configuration of said recesses so as to form an endless belt, wherein said recesses are disposed in both ends of the blank and arranged so that when the ends are brought together a pair of opposing recesses together have a dumbell configuration for receiving a connecting member, separate from said belt, of similar configuration.
