A stacking apparatus , comprising: a roller set having at least first and second portions (122, 124; 222, 224, 226a, 226c; 222, 224, 226b, 226d); a band (102; 202) passing against at least one of said first portion and said second portion of said roller set , wherein said band has an exterior surface engaging at least a portion of said roller set , and wherein said band is configured to receive a stackable item (150; 250) thereon and to move said stackable item (150; 250) to a predetermined location; and a mechanism (142, 144, 110; 242, 244) for causing said band to orbit along an orbital path (112; 212), wherein said mechanism comprises a first roller and a second roller engaging said band , wherein the first and second rollers are configured to orbit along said orbital path , wherein orbiting of said first and second rollers along said orbital path causes said band to orbit along said orbital path , wherein said first and second rollers are disposed inside said band , wherein, at said predetermined location, said band (102; 202) releases said stackable item by continuing to orbit along said orbital path , but with approximately zero total velocity, and wherein at said predetermined location, said band has a rotation that is essentially negated by the orbital movement of said band , and wherein: at a first position in which said first roller and said second roller are both on a same side of said roller set , said roller set is substantially stationary relative to its center; and at a second position in which said first roller and said second roller are on opposite sides of said roller set , said band at least partially causes said roller set to collectively rotate. a roller set having at least first and second portions (122, 124; 222, 224, 226a, 226c; 222, 224, 226b, 226d); a band (102; 202) passing against at least one of said first portion and said second portion of said roller set , wherein said band has an exterior surface engaging at least a portion of said roller set , and wherein said band is configured to receive a stackable item (150; 250) thereon and to move said stackable item (150; 250) to a predetermined location; and a mechanism (142, 144, 110; 242, 244) for causing said band to orbit along an orbital path (112; 212), wherein said mechanism comprises a first roller and a second roller engaging said band , wherein the first and second rollers are configured to orbit along said orbital path , wherein orbiting of said first and second rollers along said orbital path causes said band to orbit along said orbital path , wherein said first and second rollers are disposed inside said band , wherein, at said predetermined location, said band (102; 202) releases said stackable item by continuing to orbit along said orbital path , but with approximately zero total velocity, and wherein at said predetermined location, said band has a rotation that is essentially negated by the orbital movement of said band , and wherein: at a first position in which said first roller and said second roller are both on a same side of said roller set , said roller set is substantially stationary relative to its center; and at a second position in which said first roller and said second roller are on opposite sides of said roller set , said band at least partially causes said roller set to collectively rotate. at a first position in which said first roller and said second roller are both on a same side of said roller set , said roller set is substantially stationary relative to its center; and at a second position in which said first roller and said second roller are on opposite sides of said roller set , said band at least partially causes said roller set to collectively rotate. <EOS>
