A method for rolling together and connecting at least two plastic plates (1, 2), which respectively feature a joining side (7, 7') and a rolling side (8, 8'), on their joining sides (7, 7'), comprising the steps of: a) placing objects onto the joining side (7, 7') of a plastic plate (1, 2), wherein the ratio of the height of the objects to their width and/or length is greater than 30 %, and wherein the height of the objects is measured on an axis extending orthogonal to the joining side (7, 7') of the plastic plates, b) separately heating two plastic plates (1, 2) on their joining side (7, 7'), wherein - a temperature T erw2, at which the viscosity of the plastic lies between 10,000 Pa*s and 200,000 Pa*s, is reached on an outermost surface boundary layer, - and a temperature T erw1, at which the viscosity of the plastic lies between 200,000 Pa*s and 1,000,000 Pa*s, is reached in an internal layer that lies at a depth of the plastic plates (1, 2) corresponding to 40 % of the height of the objects, and wherein the rolling sides (8, 8') are maintained at a temperature T 2 that lies at least 10K below T erw1, c) rolling together the two plastic plates (1, 2) between two rollers (19, 20), wherein the plastic plates (1, 2) are arranged such that their joining sides (7, 7') face one another, and wherein the plastic plates (1, 2) are fed to the rollers in such an angled fashion that a gap remains between the objects and the open side of a feed side until the objects are enclosed by plastic. a) placing objects onto the joining side (7, 7') of a plastic plate (1, 2), wherein the ratio of the height of the objects to their width and/or length is greater than 30 %, and wherein the height of the objects is measured on an axis extending orthogonal to the joining side (7, 7') of the plastic plates, b) separately heating two plastic plates (1, 2) on their joining side (7, 7'), wherein - a temperature T erw2, at which the viscosity of the plastic lies between 10,000 Pa*s and 200,000 Pa*s, is reached on an outermost surface boundary layer, - and a temperature T erw1, at which the viscosity of the plastic lies between 200,000 Pa*s and 1,000,000 Pa*s, is reached in an internal layer that lies at a depth of the plastic plates (1, 2) corresponding to 40 % of the height of the objects, and wherein the rolling sides (8, 8') are maintained at a temperature T 2 that lies at least 10K below T erw1, - a temperature T erw2, at which the viscosity of the plastic lies between 10,000 Pa*s and 200,000 Pa*s, is reached on an outermost surface boundary layer, - and a temperature T erw1, at which the viscosity of the plastic lies between 200,000 Pa*s and 1,000,000 Pa*s, is reached in an internal layer that lies at a depth of the plastic plates (1, 2) corresponding to 40 % of the height of the objects, and c) rolling together the two plastic plates (1, 2) between two rollers (19, 20), wherein the plastic plates (1, 2) are arranged such that their joining sides (7, 7') face one another, and wherein the plastic plates (1, 2) are fed to the rollers in such an angled fashion that a gap remains between the objects and the open side of a feed side until the objects are enclosed by plastic.
