A frangible laminate includes first, second and third webs, and the second web is positioned between the first and third webs. The forming of the frangible laminate includes adhesively bonding a first plurality of sections of the second web to the first web, applying release material in order to inhibit at least some of any bonding between the first plurality of sections of the second web and the third web, and adhesively bonding a second plurality of sections of the second web to the third web. The frangible laminate is separated into a first laminate and a second laminate, so that the first laminate includes the first web and the first plurality of sections of the second web, and the second laminate includes the third web and the second plurality of sections of the second web.

A method allows for rapid manufacture of relatively thick adhesive coatings using a continuous process, where a single thin coating is continuously converted into a single thicker adhesive laminate. An exemplary process includes the steps of: (1) producing a web having a first surface with an adhesive layer and a second surface with a release liner; (2) slitting the web longitudinally into a first section and a second section; (3) laminating a backing film to the adhesive layer of the first section; (4) removing the release liner of the laminate of step (3) exposing the adhesive layer of the first section; and (5) laminating the second section to the laminate of step (4), wherein the adhesive layer of the laminate of step (4) is combined with the adhesive layer of the second section.

Methods, apparatus and systems for collecting thin tissue samples for imaging. Thin tissue sections may be cut from tissue samples using a microtome-quality knife. In one example, tissue samples are mounted to a substrate that is rotated such that thin tissue sections are acquired via lathing. Collection of thin tissue sections may be facilitated by a conveyor belt. Thin tissue sections may be mounted to a thin substrate (e.g., by adhering thin tissue sections to a thin substrate via a roller mechanism) that may be imaged, for example, by an electron beam (e.g., in an electron microscope). Thin tissue sections may be strengthened before cutting via a blockface thinfilm deposition technique and/or a blockface taping technique. An automated reel-to-reel imaging technique may be employed for collected/mounted tissue sections to facilitate random-access imaging of tissue sections and maintaining a comprehensive library including a large volume of samples.
