Apparatus and process are described for forming projections on a substrate for use as hook-type fasteners in touch fastening systems, wherein vibration energy may be used to soften a substrate which may be positioned between a mold and a source of vibration. The mold may include a plurality of cavities into which the softened substrate may be forced to form the projections. The substrate may comprise a film, sheet, web, composite, laminate, etc. and be useful as an attachment strip for temporary or permanent fastening. The source of vibration may be an ultrasonic horn. The process to form such projections may be operated in a continuous, semi-continuous or intermittent manner.
