ABSTRACT OF THE DISCLOSURE The invention relates to a mechanical compressive shrink- age apparatus of the type having feeding and retarding rollers arranged in opposed relation and forming a working nip, and a confining shoe having roll-confronting surface portions cooperating with the feeding roller and shoe tip portions located upstream of the working nip. The invention lies in an improvement in the confining shoe having a rigid supporting beam extending continu- ously across the full effective working width of the feeding and retarding rollers in a region generally opposite the working nip, a plurality of confining shoe segments secured individually to the supporting beam in end-to-end alignment, and a continuous liner element extending over the full working width of the aligned shoe segments, and being in roll-confronting relation to the feed- ing rolls. The liner is formed of thin, conformable sheet material and is pre-contoured to conform generally to the contours of the roll-confronting surface portions of the shoe segments, the continuous liner extends in a circumferential direction over the full confronting surface areas of the shoe segments and projects beyond the tip portions to form a working edge located between the nip and the shoe tip portions, and the working edge cooperates with the nip to form a full-width compressive shrinkage zone.
