Abstract
Abstract Porous materials, such as cloth or unglazed ceramics or porous plastics which on account of their porosity defy ordinary vacuum pick-up, are made temporarily imperforate by applying to them a temporary coating of liquid, such as water, whereupon their porosity is momentarily sufficiently inhibited to permit their pick-up and transfer by suction, as by a suction cup device. The liquid coating is deposited either by rolling or spraying the liquid onto the porous material either from above it (FIG. 1) or from beneath it either for a single layer (FIG. 2) or for a plurality of layers thereof (FIG. 3).

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
88 words
An apparatus for the vacuum pick-up of a porous material, comprising an approximately horizontal support adapted to receive and sustain the material, a liquid depositing device disposed adjacent said support and constructed and arranged to deposit a liquid layer on said material, a vacuum cup device disposed above said support in spaced relationship thereto and having a suction chamber therein, and means adapted to be connected to a suction source and connected to said vacuum cup device for raising, lowering and swinging the same relatively to said support.
Claim 2
Independent Claim
88 words
An apparatus for the vacuum pick-up of a porous material, comprising an approximately horizontal support adapted to receive and sustain the material, a liquid depositing device disposed adjacent said support and constructed and arranged to deposit a liquid layer on said material, a vacuum cup device disposed above said support in spaced relationship thereto and having a suction chamber therein, and means adapted to be connected to a suction source and connected to said vacuum cup device for raising, lowering and swinging the same relatively to said support.
Claim 3
Dependent Claim
39 words
An apparatus, according to claim 1, wherein the liquid depositing device is disposed above said support adjacent said vacuum cup device, and wherein the liquid from said liquid depositing device is deposited upon the upper surface of the material.
Claim 4
Dependent Claim
14 words
An apparatus, according to claim 1, wherein the support is a substantially imperforate member.
Claim 5
Dependent Claim
26 words
An apparatus, according to claim 1, wherein the liquid depositing device is disposed below said support on the opposite side thereof from said vacuum cup device.
Claim 6
Dependent Claim
38 words
An apparatus, according to claim 1, wherein the support is a perforated member, and wherein the liquid from said liquid depositing device passes therefrom through the perforations of said perforated member onto the lower surface of the material.
Claim 7
Dependent Claim
15 words
An apparatus, according to claim 1, wherein the liquid depositing device is a spray nozzle.
