A wet paper web transfer belt for transferring a wet paper web includes a wet paper web contacting surface for carrying the wet paper web. The wet paper web contacting surface is constituted by a resin layer. The wet paper web contacting surface includes, in the width direction, sheet edge regions for carrying the edge parts of the wet paper web and a center region for carrying the center vicinity of the wet paper web. The arithmetic average roughness Ra(&#x3bc;m) of the wet paper web contacting surface in the sheet edge regions is smaller than the arithmetic average roughness Ra(&#x3bc;m) of the wet paper web contacting surface in the center region, and prescribed roughness related equations are fulfilled.

A wet paper web transfer belt for transferring a wet paper web includes a wet paper web contacting surface for carrying the wet paper web. The wet paper web contacting surface is constituted by a resin layer, and the wet paper web contacting surface includes a wet paper web carrying region for carrying the wet paper web. A prescribed relation of the swelling rate in water of the resin layer and the surface roughness of the wet paper web contacting surface is fulfilled in accordance with the basis weight of the base paper of the wet paper web.

Provided is a belt for transferring a wet web, wherein any water mark does not appear on made paper even when a rate of feeding the belt for transferring a wet web by a roll is high. The roll side layer surface of the belt for transferring a wet web has the surface structure in which the percentage of a contact area with the roll per unit area is 10% to 75% and a surface roughness Ra is 50-150 &#x3bc;m.

Belt for transferring wet web

A work carrier includes a movable clamp unit () having resiliently connected first and second sliders () mounted on a guide rail (), a lock lever () mounted on the second slider and normally urged in a direction to move a toothed portion () into meshing engagement with a rack (), an operating lever () pivotally mounted on the second slider, and a cam mechanism () operable in response to pivotal movement of the operating lever in one direction such that the second slider is locked in position against movement relative to the guide rail via meshing engagement between the toothed portion and the rack and, subsequently, the first slider and clamp member carried thereon are forcibly displaced away from the second slider while the second slider remains locked on the guide rail.
