In a seam, for example, for paper machine clothing, interdigitating seaming loops (,) embrace deformable yarns (,) inserted between the last cross-machine direction yarns (,) and the opposed seaming loops (,). Alternatively, an insert may be in the form of a ladder-like member (,) comprising one or more cross-machine direction members (,) and a multiplicity of machine direction members (,) extending beyond the members (,) to locate the seaming loops. Also possible is the use of a strip or tape of foamed or foamable material.

Fabric seams

A phase separation apparatus such as a filter element or papermaking belt comprises an ormocer which provides abrasion resistance, cleanliness and stability.

Phase separation apparatus

A method of coating an ormocer (organically modified ceramic) on a phase separation surface of a roller of a phase separation apparatus to facilitate phase separation.

Ormocer coated papermachine clothing

A papermaking fabric primarily for use as a press felt comprises basalt fibers.

Papermaking fabric

A tobacco conveyor belt having a regular nonwoven mesh structure. The belt may incorporate an ultra-violet sensative material.

A temporary seaming bridge (62) for connecting two belt ends (26,27) during seaming comprises a bridge portion (63) with a plurality of pegs (34,35) provided at each end. The pegs (34,35) are complementary with apertures (28,29) provided in the belt ends (26,27) such that the pegs (34) at one end of the bridge engage the apertures (28) in one belt end (26) and the pegs (35) of the other end of the bridge engage the apertures (29) in the other belt end (27).

Belt seaming

Endless belt for extended nip dewatering presses

A method and apparatus is disclosed for manufacturing papermakers or like fabrics wherein preformed apertured fabric bands are joined together in spaced edge-to-edge disposition in a manner to provide substantial uniformity of construction throughout the fabric width. The invention proposed supporting the bands (11, 12) in spaced parallel disposition on a pinned roller (26) wherein the distribution and configuration of the pins (34) matches the apertures in the bands and creating an infill band in the region between adjacent preformed bands (11, 12) by feeding thermoplastic matrix material to the surface of the pinned roller in said region, causing said matrix material to flow into interstices between the pins and to bond with the material of the preformed bands. Reinforcing yarns (13) will be provided in the region between adjacent preformed bands and extending in a direction parallel to the bands and will be embodied within the matrix material of the joined structure. Transversely extending yarns may be provided on the preformed bands for like encapsulation by the matrix material of the infill band.

Edge jointing of fabrics

A method of joining the ends of a papermakers fabric wherein machine direction yarns are fringed out at the fabric ends, yarn ends being laid across a pinned plate, and yarn ends being cut back so as partially to overlie the plate. Those yarns which extend across the plate are folded back to form loops beyond the edge of the plate and a thermoplastics matrix material is applied to the plate. The matrix material is made fluid by heating and, on subsequent cooling, forms an apertured end to the fabric which presents side-by-side, outwardly extending loops. The loops at the respective fabric ends may be interdigited to receive a pintle wire, thus to bring the fabric into endless form. A variation of the method wherein a reticulate, premoulded seam element is engaged with the pinned plate for attachment to machine direction yarns of the fabric on melting of the matrix material, the seam element including axially aligned tunnels at a free edge thereof for cooperation with similar formations at an opposed fabric end and to receive a pintle wire.

Jointing of fabric ends

An ENP belt for use in the press-section of a papermaking machine is disclosed which comprises a sheet-like body part (11) having integrally formed machine-direction ribs (12) extending outwardly from the surface therefrom, there being reinforcing yarns (16) in register with respective ones of some at least of the said ribs (12) and at least partially located therein. Cross machine direction ribs (15) extending between adjacent machine direction ribs may be provided, if desired.
