ABSTRACT:
For applying adhesive to a shoe bottom an applicator (708) is provided which comprises a plurality of fingers (732) spring-urged towards the work and end portions thereof providing an adhesive-applying surface (736) to which adhesive is supplied via tubes (738) to outlets in said end portions. The applicator is capable of rotation about an axis which passes through the adhesive-applying surface (736) and in addition, the applicator can tilt about a further axis (P) which intersects said axis of rotation at the adhesive-applying surface. Drive means is also provided for effecting relative lengthwise, heightwise and widthwise movement between a shoe support (18) and a tool holder (670) by which the applicator is supported. For controlling the flow of adhesive a valve (744) is provided which is pneumatically operated and also has a suck-back feature. Moreover, the arrangement of the adhesive supply parts (740-752) and the supply of air under pressure (772-776) is such that the applicator can be rotated through 360.degree. or more without the need for thereafter reversing the direction of rotation, e.g. in order to unwind any flexible connections.
