    Abstract: A pintle wire (10) for insertion through interdigitating end loops of a belt fabric or of a spiral connector, is disclosed which is expandable after insertion into the seam, for example by way of a sheath (12) which includes a thermally activated expanding agent. This is subject to heating to expand the sheath (12) , causing the pintle wire (10) to swell and fill voids in the seam area reducing permeability in the seam and thus reducing marking of paper webs carried by the belt.

    IPC: D21F7/10

    Abstract: In a sem for e.g. papermachine clothing, interdigitating seaming loops (13, 14) embrace deformable yarns (17) inserted between the last cross-machine direction yarns (15a) and the opposed seaming loops (14, 13). Alternatively, an insert may be in the form of a ladder-like member (30) comprising one or more cross-machine direction members (31, 32, 33) and a multiplicity of machine direction members (34) extending beyond the members (31, 32, 33) to locate the seaming loops. Also possible is the use of a strip or tape of foamed or foamable material.

    Abstract: A membrane felt for a tissue making process using a Yankee or MG cylinder the membrane felt comprising a polymeric matrix membrane layer (11) and a supporting base structure (12). The polymeric matrix optionally at least partially encapsulates parallel yarns extending it at least one direction. The supporting base structure is a textile substrate. These are secured together, preferably via a batt fibre layer which may be needled between the supporting base structure and membrane layer.
